WGET(1)				   GNU Wget			       WGET(1)

NAME
       Wget - The non-interactive network downloader.

SYNOPSIS
       wget [option]...	[URL]...

DESCRIPTION
       GNU Wget	is a free utility for non-interactive download of files	from
       the Web.	 It supports HTTP, HTTPS, and FTP protocols, as	well as
       retrieval through HTTP proxies.

       Wget is non-interactive,	meaning	that it	can work in the	background,
       while the user is not logged on.	 This allows you to start a retrieval
       and disconnect from the system, letting Wget finish the work.  By
       contrast, most of the Web browsers require constant user's presence,
       which can be a great hindrance when transferring	a lot of data.

       Wget can	follow links in	HTML, XHTML, and CSS pages, to create local
       versions	of remote web sites, fully recreating the directory structure
       of the original site.  This is sometimes	referred to as "recursive
       downloading."  While doing that,	Wget respects the Robot	Exclusion
       Standard	(/robots.txt).	Wget can be instructed to convert the links in
       downloaded files	to point at the	local files, for offline viewing.

       Wget has	been designed for robustness over slow or unstable network
       connections; if a download fails	due to a network problem, it will keep
       retrying	until the whole	file has been retrieved.  If the server
       supports	regetting, it will instruct the	server to continue the
       download	from where it left off.

OPTIONS
   Option Syntax
       Since Wget uses GNU getopt to process command-line arguments, every
       option has a long form along with the short one.	 Long options are more
       convenient to remember, but take	time to	type.  You may freely mix
       different option	styles,	or specify options after the command-line
       arguments.  Thus	you may	write:

	       wget -r --tries=10 http://fly.srk.fer.hr/ -o log

       The space between the option accepting an argument and the argument may
       be omitted.  Instead of -o log you can write -olog.

       You may put several options that	do not require arguments together,
       like:

	       wget -drc <URL>

       This is completely equivalent to:

	       wget -d -r -c <URL>

       Since the options can be	specified after	the arguments, you may
       terminate them with --.	So the following will try to download URL -x,
       reporting failure to log:

	       wget -o log -- -x

       The options that	accept comma-separated lists all respect the
       convention that specifying an empty list	clears its value.  This	can be
       useful to clear the .wgetrc settings.  For instance, if your .wgetrc
       sets "exclude_directories" to /cgi-bin, the following example will
       first reset it, and then	set it to exclude /~nobody and /~somebody.
       You can also clear the lists in .wgetrc.

	       wget -X " -X /~nobody,/~somebody

       Most options that do not	accept arguments are boolean options, so named
       because their state can be captured with	a yes-or-no ("boolean")
       variable.  For example, --follow-ftp tells Wget to follow FTP links
       from HTML files and, on the other hand, --no-glob tells it not to
       perform file globbing on	FTP URLs.  A boolean option is either
       affirmative or negative (beginning with --no).  All such	options	share
       several properties.

       Unless stated otherwise,	it is assumed that the default behavior	is the
       opposite	of what	the option accomplishes.  For example, the documented
       existence of --follow-ftp assumes that the default is to	not follow FTP
       links from HTML pages.

       Affirmative options can be negated by prepending	the --no- to the
       option name; negative options can be negated by omitting	the --no-
       prefix.	This might seem	superfluous---if the default for an
       affirmative option is to	not do something, then why provide a way to
       explicitly turn it off?	But the	startup	file may in fact change	the
       default.	 For instance, using "follow_ftp = on" in .wgetrc makes	Wget
       follow FTP links	by default, and	using --no-follow-ftp is the only way
       to restore the factory default from the command line.

   Basic Startup Options
       -V
       --version
	   Display the version of Wget.

       -h
       --help
	   Print a help	message	describing all of Wget's command-line options.

       -b
       --background
	   Go to background immediately	after startup.	If no output file is
	   specified via the -o, output	is redirected to wget-log.

       -e command
       --execute command
	   Execute command as if it were a part	of .wgetrc.  A command thus
	   invoked will	be executed after the commands in .wgetrc, thus	taking
	   precedence over them.  If you need to specify more than one wgetrc
	   command, use	multiple instances of -e.

   Logging and Input File Options
       -o logfile
       --output-file=logfile
	   Log all messages to logfile.	 The messages are normally reported to
	   standard error.

       -a logfile
       --append-output=logfile
	   Append to logfile.  This is the same	as -o, only it appends to
	   logfile instead of overwriting the old log file.  If	logfile	does
	   not exist, a	new file is created.

       -d
       --debug
	   Turn	on debug output, meaning various information important to the
	   developers of Wget if it does not work properly.  Your system
	   administrator may have chosen to compile Wget without debug
	   support, in which case -d will not work.  Please note that
	   compiling with debug	support	is always safe---Wget compiled with
	   the debug support will not print any	debug info unless requested
	   with	-d.

       -q
       --quiet
	   Turn	off Wget's output.

       -v
       --verbose
	   Turn	on verbose output, with	all the	available data.	 The default
	   output is verbose.

       -nv
       --no-verbose
	   Turn	off verbose without being completely quiet (use	-q for that),
	   which means that error messages and basic information still get
	   printed.

       --report-speed=type
	   Output bandwidth as type.  The only accepted	value is bits.

       -i file
       --input-file=file
	   Read	URLs from a local or external file.  If	- is specified as
	   file, URLs are read from the	standard input.	 (Use ./- to read from
	   a file literally named -.)

	   If this function is used, no	URLs need be present on	the command
	   line.  If there are URLs both on the	command	line and in an input
	   file, those on the command lines will be the	first ones to be
	   retrieved.  If --force-html is not specified, then file should
	   consist of a	series of URLs,	one per	line.

	   However, if you specify --force-html, the document will be regarded
	   as html.  In	that case you may have problems	with relative links,
	   which you can solve either by adding	"<base href="url"_" to the
	   documents or	by specifying --base=url on the	command	line.

	   If the file is an external one, the document	will be	automatically
	   treated as html if the Content-Type matches text/html.
	   Furthermore,	the file's location will be implicitly used as base
	   href	if none	was specified.

       --input-metalink=file
	   Downloads files covered in local Metalink file. Metalink version 3
	   and 4 are supported.

       --keep-badhash
	   Keeps downloaded Metalink's files with a bad	hash. It appends
	   .badhash to the name	of Metalink's files which have a checksum
	   mismatch, except without overwriting	existing files.

       --metalink-over-http
	   Issues HTTP HEAD request instead of GET and extracts	Metalink
	   metadata from response headers. Then	it switches to Metalink
	   download.  If no valid Metalink metadata is found, it falls back to
	   ordinary HTTP download.  Enables Content-Type:
	   application/metalink4+xml files download/processing.

       --metalink-index=number
	   Set the Metalink application/metalink4+xml metaurl ordinal NUMBER.
	   From	1 to the total number of "application/metalink4+xml"
	   available.  Specify 0 or inf	to choose the first good one.
	   Metaurls, such as those from	a --metalink-over-http,	may have been
	   sorted by priority key's value; keep	this in	mind to	choose the
	   right NUMBER.

       --preferred-location
	   Set preferred location for Metalink resources. This has effect if
	   multiple resources with same	priority are available.

       -F
       --force-html
	   When	input is read from a file, force it to be treated as an	HTML
	   file.  This enables you to retrieve relative	links from existing
	   HTML	files on your local disk, by adding "<base href="url"_"	to
	   HTML, or using the --base command-line option.

       -B URL
       --base=URL
	   Resolves relative links using URL as	the point of reference,	when
	   reading links from an HTML file specified via the -i/--input-file
	   option (together with --force-html, or when the input file was
	   fetched remotely from a server describing it	as HTML). This is
	   equivalent to the presence of a "BASE" tag in the HTML input	file,
	   with	URL as the value for the "href"	attribute.

	   For instance, if you	specify	http://foo/bar/a.html for URL, and
	   Wget	reads ../baz/b.html from the input file, it would be resolved
	   to http://foo/baz/b.html.

       --config=FILE
	   Specify the location	of a startup file you wish to use.

       --rejected-log=logfile
	   Logs	all URL	rejections to logfile as comma separated values.  The
	   values include the reason of	rejection, the URL and the parent URL
	   it was found	in.

   Download Options
       --bind-address=ADDRESS
	   When	making client TCP/IP connections, bind to ADDRESS on the local
	   machine.  ADDRESS may be specified as a hostname or IP address.
	   This	option can be useful if	your machine is	bound to multiple IPs.

       --bind-dns-address=ADDRESS
	   [libcares only] This	address	overrides the route for	DNS requests.
	   If you ever need to circumvent the standard settings	from
	   /etc/resolv.conf, this option together with --dns-servers is	your
	   friend.  ADDRESS must be specified either as	IPv4 or	IPv6 address.
	   Wget	needs to be built with libcares	for this option	to be
	   available.

       --dns-servers=ADDRESSES
	   [libcares only] The given address(es) override the standard
	   nameserver addresses,  e.g. as configured in	/etc/resolv.conf.
	   ADDRESSES may be specified either as	IPv4 or	IPv6 addresses,	comma-
	   separated.  Wget needs to be	built with libcares for	this option to
	   be available.

       -t number
       --tries=number
	   Set number of tries to number. Specify 0 or inf for infinite
	   retrying.  The default is to	retry 20 times,	with the exception of
	   fatal errors	like "connection refused" or "not found" (404),	which
	   are not retried.

       -O file
       --output-document=file
	   The documents will not be written to	the appropriate	files, but all
	   will	be concatenated	together and written to	file.  If - is used as
	   file, documents will	be printed to standard output, disabling link
	   conversion.	(Use ./- to print to a file literally named -.)

	   Use of -O is	not intended to	mean simply "use the name file instead
	   of the one in the URL;" rather, it is analogous to shell
	   redirection:	wget -O	file http://foo	is intended to work like wget
	   -O -	http://foo > file; file	will be	truncated immediately, and all
	   downloaded content will be written there.

	   For this reason, -N (for timestamp-checking)	is not supported in
	   combination with -O:	since file is always newly created, it will
	   always have a very new timestamp. A warning will be issued if this
	   combination is used.

	   Similarly, using -r or -p with -O may not work as you expect: Wget
	   won't just download the first file to file and then download	the
	   rest	to their normal	names: all downloaded content will be placed
	   in file. This was disabled in version 1.11, but has been reinstated
	   (with a warning) in 1.11.2, as there	are some cases where this
	   behavior can	actually have some use.

	   A combination with -nc is only accepted if the given	output file
	   does	not exist.

	   Note	that a combination with	-k is only permitted when downloading
	   a single document, as in that case it will just convert all
	   relative URIs to external ones; -k makes no sense for multiple URIs
	   when	they're	all being downloaded to	a single file; -k can be used
	   only	when the output	is a regular file.

       -nc
       --no-clobber
	   If a	file is	downloaded more	than once in the same directory,
	   Wget's behavior depends on a	few options, including -nc.  In
	   certain cases, the local file will be clobbered, or overwritten,
	   upon	repeated download.  In other cases it will be preserved.

	   When	running	Wget without -N, -nc, -r, or -p, downloading the same
	   file	in the same directory will result in the original copy of file
	   being preserved and the second copy being named file.1.  If that
	   file	is downloaded yet again, the third copy	will be	named file.2,
	   and so on.  (This is	also the behavior with -nd, even if -r or -p
	   are in effect.)  When -nc is	specified, this	behavior is
	   suppressed, and Wget	will refuse to download	newer copies of	file.
	   Therefore, ""no-clobber"" is	actually a misnomer in this
	   mode---it's not clobbering that's prevented (as the numeric
	   suffixes were already preventing clobbering), but rather the
	   multiple version saving that's prevented.

	   When	running	Wget with -r or	-p, but	without	-N, -nd, or -nc, re-
	   downloading a file will result in the new copy simply overwriting
	   the old.  Adding -nc	will prevent this behavior, instead causing
	   the original	version	to be preserved	and any	newer copies on	the
	   server to be	ignored.

	   When	running	Wget with -N, with or without -r or -p,	the decision
	   as to whether or not	to download a newer copy of a file depends on
	   the local and remote	timestamp and size of the file.	 -nc may not
	   be specified	at the same time as -N.

	   A combination with -O/--output-document is only accepted if the
	   given output	file does not exist.

	   Note	that when -nc is specified, files with the suffixes .html or
	   .htm	will be	loaded from the	local disk and parsed as if they had
	   been	retrieved from the Web.

       --backups=backups
	   Before (over)writing	a file,	back up	an existing file by adding a
	   .1 suffix (_1 on VMS) to the	file name.  Such backup	files are
	   rotated to .2, .3, and so on, up to backups (and lost beyond	that).

       -c
       --continue
	   Continue getting a partially-downloaded file.  This is useful when
	   you want to finish up a download started by a previous instance of
	   Wget, or by another program.	 For instance:

		   wget	-c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z

	   If there is a file named ls-lR.Z in the current directory, Wget
	   will	assume that it is the first portion of the remote file,	and
	   will	ask the	server to continue the retrieval from an offset	equal
	   to the length of the	local file.

	   Note	that you don't need to specify this option if you just want
	   the current invocation of Wget to retry downloading a file should
	   the connection be lost midway through.  This	is the default
	   behavior.  -c only affects resumption of downloads started prior to
	   this	invocation of Wget, and	whose local files are still sitting
	   around.

	   Without -c, the previous example would just download	the remote
	   file	to ls-lR.Z.1, leaving the truncated ls-lR.Z file alone.

	   If you use -c on a non-empty	file, and the server does not support
	   continued downloading, Wget will restart the	download from scratch
	   and overwrite the existing file entirely.

	   Beginning with Wget 1.7, if you use -c on a file which is of	equal
	   size	as the one on the server, Wget will refuse to download the
	   file	and print an explanatory message.  The same happens when the
	   file	is smaller on the server than locally (presumably because it
	   was changed on the server since your	last download
	   attempt)---because "continuing" is not meaningful, no download
	   occurs.

	   On the other	side of	the coin, while	using -c, any file that's
	   bigger on the server	than locally will be considered	an incomplete
	   download and	only "(length(remote) -	length(local))"	bytes will be
	   downloaded and tacked onto the end of the local file.  This
	   behavior can	be desirable in	certain	cases---for instance, you can
	   use wget -c to download just	the new	portion	that's been appended
	   to a	data collection	or log file.

	   However, if the file	is bigger on the server	because	it's been
	   changed, as opposed to just appended	to, you'll end up with a
	   garbled file.  Wget has no way of verifying that the	local file is
	   really a valid prefix of the	remote file.  You need to be
	   especially careful of this when using -c in conjunction with	-r,
	   since every file will be considered as an "incomplete download"
	   candidate.

	   Another instance where you'll get a garbled file if you try to use
	   -c is if you	have a lame HTTP proxy that inserts a "transfer
	   interrupted"	string into the	local file.  In	the future a
	   "rollback" option may be added to deal with this case.

	   Note	that -c	only works with	FTP servers and	with HTTP servers that
	   support the "Range" header.

       --start-pos=OFFSET
	   Start downloading at	zero-based position OFFSET.  Offset may	be
	   expressed in	bytes, kilobytes with the `k' suffix, or megabytes
	   with	the `m'	suffix,	etc.

	   --start-pos has higher precedence over --continue.  When
	   --start-pos and --continue are both specified, wget will emit a
	   warning then	proceed	as if --continue was absent.

	   Server support for continued	download is required, otherwise
	   --start-pos cannot help.  See -c for	details.

       --progress=type
	   Select the type of the progress indicator you wish to use.  Legal
	   indicators are "dot"	and "bar".

	   The "bar" indicator is used by default.  It draws an	ASCII progress
	   bar graphics	(a.k.a "thermometer" display) indicating the status of
	   retrieval.  If the output is	not a TTY, the "dot" bar will be used
	   by default.

	   Use --progress=dot to switch	to the "dot" display.  It traces the
	   retrieval by	printing dots on the screen, each dot representing a
	   fixed amount	of downloaded data.

	   The progress	type can also take one or more parameters.  The
	   parameters vary based on the	type selected.	Parameters to type are
	   passed by appending them to the type	sperated by a colon (:)	like
	   this: --progress=type:parameter1:parameter2.

	   When	using the dotted retrieval, you	may set	the style by
	   specifying the type as dot:style.  Different	styles assign
	   different meaning to	one dot.  With the "default" style each	dot
	   represents 1K, there	are ten	dots in	a cluster and 50 dots in a
	   line.  The "binary" style has a more	"computer"-like
	   orientation---8K dots, 16-dots clusters and 48 dots per line	(which
	   makes for 384K lines).  The "mega" style is suitable	for
	   downloading large files---each dot represents 64K retrieved,	there
	   are eight dots in a cluster,	and 48 dots on each line (so each line
	   contains 3M).  If "mega" is not enough then you can use the "giga"
	   style---each	dot represents 1M retrieved, there are eight dots in a
	   cluster, and	32 dots	on each	line (so each line contains 32M).

	   With	--progress=bar,	there are currently two	possible parameters,
	   force and noscroll.

	   When	the output is not a TTY, the progress bar always falls back to
	   "dot", even if --progress=bar was passed to Wget during invocation.
	   This	behaviour can be overridden and	the "bar" output forced	by
	   using the "force" parameter as --progress=bar:force.

	   By default, the bar style progress bar scroll the name of the file
	   from	left to	right for the file being downloaded if the filename
	   exceeds the maximum length allotted for its display.	 In certain
	   cases, such as with --progress=bar:force, one may not want the
	   scrolling filename in the progress bar.  By passing the "noscroll"
	   parameter, Wget can be forced to display as much of the filename as
	   possible without scrolling through it.

	   Note	that you can set the default style using the "progress"
	   command in .wgetrc.	That setting may be overridden from the
	   command line.  For example, to force	the bar	output without
	   scrolling, use --progress=bar:force:noscroll.

       --show-progress
	   Force wget to display the progress bar in any verbosity.

	   By default, wget only displays the progress bar in verbose mode.
	   One may however, want wget to display the progress bar on screen in
	   conjunction with any	other verbosity	modes like --no-verbose	or
	   --quiet.  This is often a desired a property	when invoking wget to
	   download several small/large	files.	In such	a case,	wget could
	   simply be invoked with this parameter to get	a much cleaner output
	   on the screen.

	   This	option will also force the progress bar	to be printed to
	   stderr when used alongside the --logfile option.

       -N
       --timestamping
	   Turn	on time-stamping.

       --no-if-modified-since
	   Do not send If-Modified-Since header	in -N mode. Send preliminary
	   HEAD	request	instead. This has only effect in -N mode.

       --no-use-server-timestamps
	   Don't set the local file's timestamp	by the one on the server.

	   By default, when a file is downloaded, its timestamps are set to
	   match those from the	remote file. This allows the use of
	   --timestamping on subsequent	invocations of wget. However, it is
	   sometimes useful to base the	local file's timestamp on when it was
	   actually downloaded;	for that purpose, the
	   --no-use-server-timestamps option has been provided.

       -S
       --server-response
	   Print the headers sent by HTTP servers and responses	sent by	FTP
	   servers.

       --spider
	   When	invoked	with this option, Wget will behave as a	Web spider,
	   which means that it will not	download the pages, just check that
	   they	are there.  For	example, you can use Wget to check your
	   bookmarks:

		   wget	--spider --force-html -i bookmarks.html

	   This	feature	needs much more	work for Wget to get close to the
	   functionality of real web spiders.

       -T seconds
       --timeout=seconds
	   Set the network timeout to seconds seconds.	This is	equivalent to
	   specifying --dns-timeout, --connect-timeout,	and --read-timeout,
	   all at the same time.

	   When	interacting with the network, Wget can check for timeout and
	   abort the operation if it takes too long.  This prevents anomalies
	   like	hanging	reads and infinite connects.  The only timeout enabled
	   by default is a 900-second read timeout.  Setting a timeout to 0
	   disables it altogether.  Unless you know what you are doing,	it is
	   best	not to change the default timeout settings.

	   All timeout-related options accept decimal values, as well as
	   subsecond values.  For example, 0.1 seconds is a legal (though
	   unwise) choice of timeout.  Subsecond timeouts are useful for
	   checking server response times or for testing network latency.

       --dns-timeout=seconds
	   Set the DNS lookup timeout to seconds seconds.  DNS lookups that
	   don't complete within the specified time will fail.	By default,
	   there is no timeout on DNS lookups, other than that implemented by
	   system libraries.

       --connect-timeout=seconds
	   Set the connect timeout to seconds seconds.	TCP connections	that
	   take	longer to establish will be aborted.  By default, there	is no
	   connect timeout, other than that implemented	by system libraries.

       --read-timeout=seconds
	   Set the read	(and write) timeout to seconds seconds.	 The "time" of
	   this	timeout	refers to idle time: if, at any	point in the download,
	   no data is received for more	than the specified number of seconds,
	   reading fails and the download is restarted.	 This option does not
	   directly affect the duration	of the entire download.

	   Of course, the remote server	may choose to terminate	the connection
	   sooner than this option requires.  The default read timeout is 900
	   seconds.

       --limit-rate=amount
	   Limit the download speed to amount bytes per	second.	 Amount	may be
	   expressed in	bytes, kilobytes with the k suffix, or megabytes with
	   the m suffix.  For example, --limit-rate=20k	will limit the
	   retrieval rate to 20KB/s.  This is useful when, for whatever
	   reason, you don't want Wget to consume the entire available
	   bandwidth.

	   This	option allows the use of decimal numbers, usually in
	   conjunction with power suffixes; for	example, --limit-rate=2.5k is
	   a legal value.

	   Note	that Wget implements the limiting by sleeping the appropriate
	   amount of time after	a network read that took less time than
	   specified by	the rate.  Eventually this strategy causes the TCP
	   transfer to slow down to approximately the specified	rate.
	   However, it may take	some time for this balance to be achieved, so
	   don't be surprised if limiting the rate doesn't work	well with very
	   small files.

       -w seconds
       --wait=seconds
	   Wait	the specified number of	seconds	between	the retrievals.	 Use
	   of this option is recommended, as it	lightens the server load by
	   making the requests less frequent.  Instead of in seconds, the time
	   can be specified in minutes using the "m" suffix, in	hours using
	   "h" suffix, or in days using	"d" suffix.

	   Specifying a	large value for	this option is useful if the network
	   or the destination host is down, so that Wget can wait long enough
	   to reasonably expect	the network error to be	fixed before the
	   retry.  The waiting interval	specified by this function is
	   influenced by "--random-wait", which	see.

       --waitretry=seconds
	   If you don't	want Wget to wait between every	retrieval, but only
	   between retries of failed downloads,	you can	use this option.  Wget
	   will	use linear backoff, waiting 1 second after the first failure
	   on a	given file, then waiting 2 seconds after the second failure on
	   that	file, up to the	maximum	number of seconds you specify.

	   By default, Wget will assume	a value	of 10 seconds.

       --random-wait
	   Some	web sites may perform log analysis to identify retrieval
	   programs such as Wget by looking for	statistically significant
	   similarities	in the time between requests. This option causes the
	   time	between	requests to vary between 0.5 and 1.5 * wait seconds,
	   where wait was specified using the --wait option, in	order to mask
	   Wget's presence from	such analysis.

	   A 2001 article in a publication devoted to development on a popular
	   consumer platform provided code to perform this analysis on the
	   fly.	 Its author suggested blocking at the class C address level to
	   ensure automated retrieval programs were blocked despite changing
	   DHCP-supplied addresses.

	   The --random-wait option was	inspired by this ill-advised
	   recommendation to block many	unrelated users	from a web site	due to
	   the actions of one.

       --no-proxy
	   Don't use proxies, even if the appropriate *_proxy environment
	   variable is defined.

       -Q quota
       --quota=quota
	   Specify download quota for automatic	retrievals.  The value can be
	   specified in	bytes (default), kilobytes (with k suffix), or
	   megabytes (with m suffix).

	   Note	that quota will	never affect downloading a single file.	 So if
	   you specify wget -Q10k https://example.com/ls-lR.gz,	all of the
	   ls-lR.gz will be downloaded.	 The same goes even when several URLs
	   are specified on the	command-line.  However,	quota is respected
	   when	retrieving either recursively, or from an input	file.  Thus
	   you may safely type wget -Q2m -i sites---download will be aborted
	   when	the quota is exceeded.

	   Setting quota to 0 or to inf	unlimits the download quota.

       --no-dns-cache
	   Turn	off caching of DNS lookups.  Normally, Wget remembers the IP
	   addresses it	looked up from DNS so it doesn't have to repeatedly
	   contact the DNS server for the same (typically small) set of	hosts
	   it retrieves	from.  This cache exists in memory only; a new Wget
	   run will contact DNS	again.

	   However, it has been	reported that in some situations it is not
	   desirable to	cache host names, even for the duration	of a short-
	   running application like Wget.  With	this option Wget issues	a new
	   DNS lookup (more precisely, a new call to "gethostbyname" or
	   "getaddrinfo") each time it makes a new connection.	Please note
	   that	this option will not affect caching that might be performed by
	   the resolving library or by an external caching layer, such as
	   NSCD.

	   If you don't	understand exactly what	this option does, you probably
	   won't need it.

       --restrict-file-names=modes
	   Change which	characters found in remote URLs	must be	escaped	during
	   generation of local filenames.  Characters that are restricted by
	   this	option are escaped, i.e. replaced with %HH, where HH is	the
	   hexadecimal number that corresponds to the restricted character.
	   This	option may also	be used	to force all alphabetical cases	to be
	   either lower- or uppercase.

	   By default, Wget escapes the	characters that	are not	valid or safe
	   as part of file names on your operating system, as well as control
	   characters that are typically unprintable.  This option is useful
	   for changing	these defaults,	perhaps	because	you are	downloading to
	   a non-native	partition, or because you want to disable escaping of
	   the control characters, or you want to further restrict characters
	   to only those in the	ASCII range of values.

	   The modes are a comma-separated set of text values. The acceptable
	   values are unix, windows, nocontrol,	ascii, lowercase, and
	   uppercase. The values unix and windows are mutually exclusive (one
	   will	override the other), as	are lowercase and uppercase. Those
	   last	are special cases, as they do not change the set of characters
	   that	would be escaped, but rather force local file paths to be
	   converted either to lower- or uppercase.

	   When	"unix" is specified, Wget escapes the character	/ and the
	   control characters in the ranges 0--31 and 128--159.	 This is the
	   default on Unix-like	operating systems.

	   When	"windows" is given, Wget escapes the characters	\, |, /, :, ?,
	   ", *, <, >, and the control characters in the ranges	0--31 and
	   128--159.  In addition to this, Wget	in Windows mode	uses + instead
	   of :	to separate host and port in local file	names, and uses	@
	   instead of ?	to separate the	query portion of the file name from
	   the rest.  Therefore, a URL that would be saved as
	   www.xemacs.org:4300/search.pl?input=blah in Unix mode would be
	   saved as www.xemacs.org+4300/search.pl@input=blah in	Windows	mode.
	   This	mode is	the default on Windows.

	   If you specify nocontrol, then the escaping of the control
	   characters is also switched off. This option	may make sense when
	   you are downloading URLs whose names	contain	UTF-8 characters, on a
	   system which	can save and display filenames in UTF-8	(some possible
	   byte	values used in UTF-8 byte sequences fall in the	range of
	   values designated by	Wget as	"controls").

	   The ascii mode is used to specify that any bytes whose values are
	   outside the range of	ASCII characters (that is, greater than	127)
	   shall be escaped. This can be useful	when saving filenames whose
	   encoding does not match the one used	locally.

       -4
       --inet4-only
       -6
       --inet6-only
	   Force connecting to IPv4 or IPv6 addresses.	With --inet4-only or
	   -4, Wget will only connect to IPv4 hosts, ignoring AAAA records in
	   DNS,	and refusing to	connect	to IPv6	addresses specified in URLs.
	   Conversely, with --inet6-only or -6,	Wget will only connect to IPv6
	   hosts and ignore A records and IPv4 addresses.

	   Neither options should be needed normally.  By default, an
	   IPv6-aware Wget will	use the	address	family specified by the	host's
	   DNS record.	If the DNS responds with both IPv4 and IPv6 addresses,
	   Wget	will try them in sequence until	it finds one it	can connect
	   to.	(Also see "--prefer-family" option described below.)

	   These options can be	used to	deliberately force the use of IPv4 or
	   IPv6	address	families on dual family	systems, usually to aid
	   debugging or	to deal	with broken network configuration.  Only one
	   of --inet6-only and --inet4-only may	be specified at	the same time.
	   Neither option is available in Wget compiled	without	IPv6 support.

       --prefer-family=none/IPv4/IPv6
	   When	given a	choice of several addresses, connect to	the addresses
	   with	specified address family first.	 The address order returned by
	   DNS is used without change by default.

	   This	avoids spurious	errors and connect attempts when accessing
	   hosts that resolve to both IPv6 and IPv4 addresses from IPv4
	   networks.  For example, www.kame.net	resolves to
	   2001:200:0:8002:203:47ff:fea5:3085 and to 203.178.141.194.  When
	   the preferred family	is "IPv4", the IPv4 address is used first;
	   when	the preferred family is	"IPv6",	the IPv6 address is used
	   first; if the specified value is "none", the	address	order returned
	   by DNS is used without change.

	   Unlike -4 and -6, this option doesn't inhibit access	to any address
	   family, it only changes the order in	which the addresses are
	   accessed.  Also note	that the reordering performed by this option
	   is stable---it doesn't affect order of addresses of the same
	   family.  That is, the relative order	of all IPv4 addresses and of
	   all IPv6 addresses remains intact in	all cases.

       --retry-connrefused
	   Consider "connection	refused" a transient error and try again.
	   Normally Wget gives up on a URL when	it is unable to	connect	to the
	   site	because	failure	to connect is taken as a sign that the server
	   is not running at all and that retries would	not help.  This	option
	   is for mirroring unreliable sites whose servers tend	to disappear
	   for short periods of	time.

       --user=user
       --password=password
	   Specify the username	user and password password for both FTP	and
	   HTTP	file retrieval.	 These parameters can be overridden using the
	   --ftp-user and --ftp-password options for FTP connections and the
	   --http-user and --http-password options for HTTP connections.

       --ask-password
	   Prompt for a	password for each connection established. Cannot be
	   specified when --password is	being used, because they are mutually
	   exclusive.

       --use-askpass=command
	   Prompt for a	user and password using	the specified command.	If no
	   command is specified	then the command in the	environment variable
	   WGET_ASKPASS	is used.  If WGET_ASKPASS is not set then the command
	   in the environment variable SSH_ASKPASS is used.

	   You can set the default command for use-askpass in the .wgetrc.
	   That	setting	may be overridden from the command line.

       --no-iri
	   Turn	off internationalized URI (IRI)	support. Use --iri to turn it
	   on. IRI support is activated	by default.

	   You can set the default state of IRI	support	using the "iri"
	   command in .wgetrc. That setting may	be overridden from the command
	   line.

       --local-encoding=encoding
	   Force Wget to use encoding as the default system encoding. That
	   affects how Wget converts URLs specified as arguments from locale
	   to UTF-8 for	IRI support.

	   Wget	use the	function "nl_langinfo()" and then the "CHARSET"
	   environment variable	to get the locale. If it fails,	ASCII is used.

	   You can set the default local encoding using	the "local_encoding"
	   command in .wgetrc. That setting may	be overridden from the command
	   line.

       --remote-encoding=encoding
	   Force Wget to use encoding as the default remote server encoding.
	   That	affects	how Wget converts URIs found in	files from remote
	   encoding to UTF-8 during a recursive	fetch. This options is only
	   useful for IRI support, for the interpretation of non-ASCII
	   characters.

	   For HTTP, remote encoding can be found in HTTP "Content-Type"
	   header and in HTML "Content-Type http-equiv"	meta tag.

	   You can set the default encoding using the "remoteencoding" command
	   in .wgetrc. That setting may	be overridden from the command line.

       --unlink
	   Force Wget to unlink	file instead of	clobbering existing file. This
	   option is useful for	downloading to the directory with hardlinks.

   Directory Options
       -nd
       --no-directories
	   Do not create a hierarchy of	directories when retrieving
	   recursively.	 With this option turned on, all files will get	saved
	   to the current directory, without clobbering	(if a name shows up
	   more	than once, the filenames will get extensions .n).

       -x
       --force-directories
	   The opposite	of -nd---create	a hierarchy of directories, even if
	   one would not have been created otherwise.  E.g. wget -x
	   http://fly.srk.fer.hr/robots.txt will save the downloaded file to
	   fly.srk.fer.hr/robots.txt.

       -nH
       --no-host-directories
	   Disable generation of host-prefixed directories.  By	default,
	   invoking Wget with -r http://fly.srk.fer.hr/	will create a
	   structure of	directories beginning with fly.srk.fer.hr/.  This
	   option disables such	behavior.

       --protocol-directories
	   Use the protocol name as a directory	component of local file	names.
	   For example,	with this option, wget -r http://host will save	to
	   http/host/... rather	than just to host/....

       --cut-dirs=number
	   Ignore number directory components.	This is	useful for getting a
	   fine-grained	control	over the directory where recursive retrieval
	   will	be saved.

	   Take, for example, the directory at
	   ftp://ftp.xemacs.org/pub/xemacs/.  If you retrieve it with -r, it
	   will	be saved locally under ftp.xemacs.org/pub/xemacs/.  While the
	   -nH option can remove the ftp.xemacs.org/ part, you are still stuck
	   with	pub/xemacs.  This is where --cut-dirs comes in handy; it makes
	   Wget	not "see" number remote	directory components.  Here are
	   several examples of how --cut-dirs option works.

		   No options	     ->	ftp.xemacs.org/pub/xemacs/
		   -nH		     ->	pub/xemacs/
		   -nH --cut-dirs=1  ->	xemacs/
		   -nH --cut-dirs=2  ->	.

		   --cut-dirs=1	     ->	ftp.xemacs.org/xemacs/
		   ...

	   If you just want to get rid of the directory	structure, this	option
	   is similar to a combination of -nd and -P.  However,	unlike -nd,
	   --cut-dirs does not lose with subdirectories---for instance,	with
	   -nH --cut-dirs=1, a beta/ subdirectory will be placed to
	   xemacs/beta,	as one would expect.

       -P prefix
       --directory-prefix=prefix
	   Set directory prefix	to prefix.  The	directory prefix is the
	   directory where all other files and subdirectories will be saved
	   to, i.e. the	top of the retrieval tree.  The	default	is . (the
	   current directory).

   HTTP	Options
       --default-page=name
	   Use name as the default file	name when it isn't known (i.e.,	for
	   URLs	that end in a slash), instead of index.html.

       -E
       --adjust-extension
	   If a	file of	type application/xhtml+xml or text/html	is downloaded
	   and the URL does not	end with the regexp \.[Hh][Tt][Mm][Ll]?, this
	   option will cause the suffix	.html to be appended to	the local
	   filename.  This is useful, for instance, when you're	mirroring a
	   remote site that uses .asp pages, but you want the mirrored pages
	   to be viewable on your stock	Apache server.	Another	good use for
	   this	is when	you're downloading CGI-generated materials.  A URL
	   like	http://site.com/article.cgi?25 will be saved as
	   article.cgi?25.html.

	   Note	that filenames changed in this way will	be re-downloaded every
	   time	you re-mirror a	site, because Wget can't tell that the local
	   X.html file corresponds to remote URL X (since it doesn't yet know
	   that	the URL	produces output	of type	text/html or
	   application/xhtml+xml.

	   As of version 1.12, Wget will also ensure that any downloaded files
	   of type text/css end	in the suffix .css, and	the option was renamed
	   from	--html-extension, to better reflect its	new behavior. The old
	   option name is still	acceptable, but	should now be considered
	   deprecated.

	   At some point in the	future,	this option may	well be	expanded to
	   include suffixes for	other types of content,	including content
	   types that are not parsed by	Wget.

       --http-user=user
       --http-password=password
	   Specify the username	user and password password on an HTTP server.
	   According to	the type of the	challenge, Wget	will encode them using
	   either the "basic" (insecure), the "digest",	or the Windows "NTLM"
	   authentication scheme.

	   Another way to specify username and password	is in the URL itself.
	   Either method reveals your password to anyone who bothers to	run
	   "ps".  To prevent the passwords from	being seen, use	the
	   --use-askpass or store them in .wgetrc or .netrc, and make sure to
	   protect those files from other users	with "chmod".  If the
	   passwords are really	important, do not leave	them lying in those
	   files either---edit the files and delete them after Wget has
	   started the download.

       --no-http-keep-alive
	   Turn	off the	"keep-alive" feature for HTTP downloads.  Normally,
	   Wget	asks the server	to keep	the connection open so that, when you
	   download more than one document from	the same server, they get
	   transferred over the	same TCP connection.  This saves time and at
	   the same time reduces the load on the server.

	   This	option is useful when, for some	reason,	persistent (keep-
	   alive) connections don't work for you, for example due to a server
	   bug or due to the inability of server-side scripts to cope with the
	   connections.

       --no-cache
	   Disable server-side cache.  In this case, Wget will send the	remote
	   server an appropriate directive (Pragma: no-cache) to get the file
	   from	the remote service, rather than	returning the cached version.
	   This	is especially useful for retrieving and	flushing out-of-date
	   documents on	proxy servers.

	   Caching is allowed by default.

       --no-cookies
	   Disable the use of cookies.	Cookies	are a mechanism	for
	   maintaining server-side state.  The server sends the	client a
	   cookie using	the "Set-Cookie" header, and the client	responds with
	   the same cookie upon	further	requests.  Since cookies allow the
	   server owners to keep track of visitors and for sites to exchange
	   this	information, some consider them	a breach of privacy.  The
	   default is to use cookies; however, storing cookies is not on by
	   default.

       --load-cookies file
	   Load	cookies	from file before the first HTTP	retrieval.  file is a
	   textual file	in the format originally used by Netscape's
	   cookies.txt file.

	   You will typically use this option when mirroring sites that
	   require that	you be logged in to access some	or all of their
	   content.  The login process typically works by the web server
	   issuing an HTTP cookie upon receiving and verifying your
	   credentials.	 The cookie is then resent by the browser when
	   accessing that part of the site, and	so proves your identity.

	   Mirroring such a site requires Wget to send the same	cookies	your
	   browser sends when communicating with the site.  This is achieved
	   by --load-cookies---simply point Wget to the	location of the
	   cookies.txt file, and it will send the same cookies your browser
	   would send in the same situation.  Different	browsers keep textual
	   cookie files	in different locations:

	   "Netscape 4.x."
	       The cookies are in ~/.netscape/cookies.txt.

	   "Mozilla and	Netscape 6.x."
	       Mozilla's cookie	file is	also named cookies.txt,	located
	       somewhere under ~/.mozilla, in the directory of your profile.
	       The full	path usually ends up looking somewhat like
	       ~/.mozilla/default/some-weird-string/cookies.txt.

	   "Internet Explorer."
	       You can produce a cookie	file Wget can use by using the File
	       menu, Import and	Export,	Export Cookies.	 This has been tested
	       with Internet Explorer 5; it is not guaranteed to work with
	       earlier versions.

	   "Other browsers."
	       If you are using	a different browser to create your cookies,
	       --load-cookies will only	work if	you can	locate or produce a
	       cookie file in the Netscape format that Wget expects.

	   If you cannot use --load-cookies, there might still be an
	   alternative.	 If your browser supports a "cookie manager", you can
	   use it to view the cookies used when	accessing the site you're
	   mirroring.  Write down the name and value of	the cookie, and
	   manually instruct Wget to send those	cookies, bypassing the
	   "official" cookie support:

		   wget	--no-cookies --header "Cookie: <name>=<value>"

       --save-cookies file
	   Save	cookies	to file	before exiting.	 This will not save cookies
	   that	have expired or	that have no expiry time (so-called "session
	   cookies"), but also see --keep-session-cookies.

       --keep-session-cookies
	   When	specified, causes --save-cookies to also save session cookies.
	   Session cookies are normally	not saved because they are meant to be
	   kept	in memory and forgotten	when you exit the browser.  Saving
	   them	is useful on sites that	require	you to log in or to visit the
	   home	page before you	can access some	pages.	With this option,
	   multiple Wget runs are considered a single browser session as far
	   as the site is concerned.

	   Since the cookie file format	does not normally carry	session
	   cookies, Wget marks them with an expiry timestamp of	0.  Wget's
	   --load-cookies recognizes those as session cookies, but it might
	   confuse other browsers.  Also note that cookies so loaded will be
	   treated as other session cookies, which means that if you want
	   --save-cookies to preserve them again, you must use
	   --keep-session-cookies again.

       --ignore-length
	   Unfortunately, some HTTP servers (CGI programs, to be more precise)
	   send	out bogus "Content-Length" headers, which makes	Wget go	wild,
	   as it thinks	not all	the document was retrieved.  You can spot this
	   syndrome if Wget retries getting the	same document again and	again,
	   each	time claiming that the (otherwise normal) connection has
	   closed on the very same byte.

	   With	this option, Wget will ignore the "Content-Length" header---as
	   if it never existed.

       --header=header-line
	   Send	header-line along with the rest	of the headers in each HTTP
	   request.  The supplied header is sent as-is,	which means it must
	   contain name	and value separated by colon, and must not contain
	   newlines.

	   You may define more than one	additional header by specifying
	   --header more than once.

		   wget	--header='Accept-Charset: iso-8859-2' \
			--header='Accept-Language: hr'	      \
			  http://fly.srk.fer.hr/

	   Specification of an empty string as the header value	will clear all
	   previous user-defined headers.

	   As of Wget 1.10, this option	can be used to override	headers
	   otherwise generated automatically.  This example instructs Wget to
	   connect to localhost, but to	specify	foo.bar	in the "Host" header:

		   wget	--header="Host:	foo.bar" http://localhost/

	   In versions of Wget prior to	1.10 such use of --header caused
	   sending of duplicate	headers.

       --max-redirect=number
	   Specifies the maximum number	of redirections	to follow for a
	   resource.  The default is 20, which is usually far more than
	   necessary. However, on those	occasions where	you want to allow more
	   (or fewer), this is the option to use.

       --proxy-user=user
       --proxy-password=password
	   Specify the username	user and password password for authentication
	   on a	proxy server.  Wget will encode	them using the "basic"
	   authentication scheme.

	   Security considerations similar to those with --http-password
	   pertain here	as well.

       --referer=url
	   Include `Referer: url' header in HTTP request.  Useful for
	   retrieving documents	with server-side processing that assume	they
	   are always being retrieved by interactive web browsers and only
	   come	out properly when Referer is set to one	of the pages that
	   point to them.

       --save-headers
	   Save	the headers sent by the	HTTP server to the file, preceding the
	   actual contents, with an empty line as the separator.

       -U agent-string
       --user-agent=agent-string
	   Identify as agent-string to the HTTP	server.

	   The HTTP protocol allows the	clients	to identify themselves using a
	   "User-Agent"	header field.  This enables distinguishing the WWW
	   software, usually for statistical purposes or for tracing of
	   protocol violations.	 Wget normally identifies as Wget/version,
	   version being the current version number of Wget.

	   However, some sites have been known to impose the policy of
	   tailoring the output	according to the "User-Agent"-supplied
	   information.	 While this is not such	a bad idea in theory, it has
	   been	abused by servers denying information to clients other than
	   (historically) Netscape or, more frequently,	Microsoft Internet
	   Explorer.  This option allows you to	change the "User-Agent"	line
	   issued by Wget.  Use	of this	option is discouraged, unless you
	   really know what you	are doing.

	   Specifying empty user agent with --user-agent="" instructs Wget not
	   to send the "User-Agent" header in HTTP requests.

       --post-data=string
       --post-file=file
	   Use POST as the method for all HTTP requests	and send the specified
	   data	in the request body.  --post-data sends	string as data,
	   whereas --post-file sends the contents of file.  Other than that,
	   they	work in	exactly	the same way. In particular, they both expect
	   content of the form "key1=value1&key2=value2", with percent-
	   encoding for	special	characters; the	only difference	is that	one
	   expects its content as a command-line parameter and the other
	   accepts its content from a file. In particular, --post-file is not
	   for transmitting files as form attachments: those must appear as
	   "key=value" data (with appropriate percent-coding) just like
	   everything else. Wget does not currently support
	   "multipart/form-data" for transmitting POST data; only
	   "application/x-www-form-urlencoded".	Only one of --post-data	and
	   --post-file should be specified.

	   Please note that wget does not require the content to be of the
	   form	"key1=value1&key2=value2", and neither does it test for	it.
	   Wget	will simply transmit whatever data is provided to it. Most
	   servers however expect the POST data	to be in the above format when
	   processing HTML Forms.

	   When	sending	a POST request using the --post-file option, Wget
	   treats the file as a	binary file and	will send every	character in
	   the POST request without stripping trailing newline or formfeed
	   characters. Any other control characters in the text	will also be
	   sent	as-is in the POST request.

	   Please be aware that	Wget needs to know the size of the POST	data
	   in advance.	Therefore the argument to "--post-file"	must be	a
	   regular file; specifying a FIFO or something	like /dev/stdin	won't
	   work.  It's not quite clear how to work around this limitation
	   inherent in HTTP/1.0.  Although HTTP/1.1 introduces chunked
	   transfer that doesn't require knowing the request length in
	   advance, a client can't use chunked unless it knows it's talking to
	   an HTTP/1.1 server.	And it can't know that until it	receives a
	   response, which in turn requires the	request	to have	been completed
	   -- a	chicken-and-egg	problem.

	   Note: As of version 1.15 if Wget is redirected after	the POST
	   request is completed, its behaviour will depend on the response
	   code	returned by the	server.	 In case of a 301 Moved	Permanently,
	   302 Moved Temporarily or 307	Temporary Redirect, Wget will, in
	   accordance with RFC2616, continue to	send a POST request.  In case
	   a server wants the client to	change the Request method upon
	   redirection,	it should send a 303 See Other response	code.

	   This	example	shows how to log in to a server	using POST and then
	   proceed to download the desired pages, presumably only accessible
	   to authorized users:

		   # Log in to the server.  This can be	done only once.
		   wget	--save-cookies cookies.txt \
			--post-data 'user=foo&password=bar' \
			http://example.com/auth.php

		   # Now grab the page or pages	we care	about.
		   wget	--load-cookies cookies.txt \
			-p http://example.com/interesting/article.php

	   If the server is using session cookies to track user
	   authentication, the above will not work because --save-cookies will
	   not save them (and neither will browsers) and the cookies.txt file
	   will	be empty.  In that case	use --keep-session-cookies along with
	   --save-cookies to force saving of session cookies.

       --method=HTTP-Method
	   For the purpose of RESTful scripting, Wget allows sending of	other
	   HTTP	Methods	without	the need to explicitly set them	using
	   --header=Header-Line.  Wget will use	whatever string	is passed to
	   it after --method as	the HTTP Method	to the server.

       --body-data=Data-String
       --body-file=Data-File
	   Must	be set when additional data needs to be	sent to	the server
	   along with the Method specified using --method.  --body-data	sends
	   string as data, whereas --body-file sends the contents of file.
	   Other than that, they work in exactly the same way.

	   Currently, --body-file is not for transmitting files	as a whole.
	   Wget	does not currently support "multipart/form-data" for
	   transmitting	data; only "application/x-www-form-urlencoded".	In the
	   future, this	may be changed so that wget sends the --body-file as a
	   complete file instead of sending its	contents to the	server.	Please
	   be aware that Wget needs to know the	contents of BODY Data in
	   advance, and	hence the argument to --body-file should be a regular
	   file. See --post-file for a more detailed explanation.  Only	one of
	   --body-data and --body-file should be specified.

	   If Wget is redirected after the request is completed, Wget will
	   suspend the current method and send a GET request till the
	   redirection is completed.  This is true for all redirection
	   response codes except 307 Temporary Redirect	which is used to
	   explicitly specify that the request method should not change.
	   Another exception is	when the method	is set to "POST", in which
	   case	the redirection	rules specified	under --post-data are
	   followed.

       --content-disposition
	   If this is set to on, experimental (not fully-functional) support
	   for "Content-Disposition" headers is	enabled. This can currently
	   result in extra round-trips to the server for a "HEAD" request, and
	   is known to suffer from a few bugs, which is	why it is not
	   currently enabled by	default.

	   This	option is useful for some file-downloading CGI programs	that
	   use "Content-Disposition" headers to	describe what the name of a
	   downloaded file should be.

	   When	combined with --metalink-over-http and --trust-server-names, a
	   Content-Type: application/metalink4+xml file	is named using the
	   "Content-Disposition" filename field, if available.

       --content-on-error
	   If this is set to on, wget will not skip the	content	when the
	   server responds with	a http status code that	indicates error.

       --trust-server-names
	   If this is set, on a	redirect, the local file name will be based on
	   the redirection URL.	 By default the	local file name	is based on
	   the original	URL.  When doing recursive retrieving this can be
	   helpful because in many web sites redirected	URLs correspond	to an
	   underlying file structure, while link URLs do not.

       --auth-no-challenge
	   If this option is given, Wget will send Basic HTTP authentication
	   information (plaintext username and password) for all requests,
	   just	like Wget 1.10.2 and prior did by default.

	   Use of this option is not recommended, and is intended only to
	   support some	few obscure servers, which never send HTTP
	   authentication challenges, but accept unsolicited auth info,	say,
	   in addition to form-based authentication.

       --retry-on-http-error=code[,code,...]
	   Consider given HTTP response	codes as non-fatal, transient errors.
	   Supply a comma-separated list of 3-digit HTTP response codes	as
	   argument. Useful to work around special circumstances where retries
	   are required, but the server	responds with an error code normally
	   not retried by Wget.	Such errors might be 503 (Service Unavailable)
	   and 429 (Too	Many Requests).	Retries	enabled	by this	option are
	   performed subject to	the normal retry timing	and retry count
	   limitations of Wget.

	   Using this option is	intended to support special use	cases only and
	   is generally	not recommended, as it can force retries even in cases
	   where the server is actually	trying to decrease its load. Please
	   use wisely and only if you know what	you are	doing.

   HTTPS (SSL/TLS) Options
       To support encrypted HTTP (HTTPS) downloads, Wget must be compiled with
       an external SSL library.	The current default is GnuTLS.	In addition,
       Wget also supports HSTS (HTTP Strict Transport Security).  If Wget is
       compiled	without	SSL support, none of these options are available.

       --secure-protocol=protocol
	   Choose the secure protocol to be used.  Legal values	are auto,
	   SSLv2, SSLv3, TLSv1,	TLSv1_1, TLSv1_2 and PFS.  If auto is used,
	   the SSL library is given the	liberty	of choosing the	appropriate
	   protocol automatically, which is achieved by	sending	a TLSv1
	   greeting. This is the default.

	   Specifying SSLv2, SSLv3, TLSv1, TLSv1_1 or TLSv1_2 forces the use
	   of the corresponding	protocol.  This	is useful when talking to old
	   and buggy SSL server	implementations	that make it hard for the
	   underlying SSL library to choose the	correct	protocol version.
	   Fortunately,	such servers are quite rare.

	   Specifying PFS enforces the use of the so-called Perfect Forward
	   Security cipher suites. In short, PFS adds security by creating a
	   one-time key	for each SSL connection. It has	a bit more CPU impact
	   on client and server.  We use known to be secure ciphers (e.g. no
	   MD4)	and the	TLS protocol.

       --https-only
	   When	in recursive mode, only	HTTPS links are	followed.

       --no-check-certificate
	   Don't check the server certificate against the available
	   certificate authorities.  Also don't	require	the URL	host name to
	   match the common name presented by the certificate.

	   As of Wget 1.10, the	default	is to verify the server's certificate
	   against the recognized certificate authorities, breaking the	SSL
	   handshake and aborting the download if the verification fails.
	   Although this provides more secure downloads, it does break
	   interoperability with some sites that worked	with previous Wget
	   versions, particularly those	using self-signed, expired, or
	   otherwise invalid certificates.  This option	forces an "insecure"
	   mode	of operation that turns	the certificate	verification errors
	   into	warnings and allows you	to proceed.

	   If you encounter "certificate verification" errors or ones saying
	   that	"common	name doesn't match requested host name", you can use
	   this	option to bypass the verification and proceed with the
	   download.  Only use this option if you are otherwise	convinced of
	   the site's authenticity, or if you really don't care	about the
	   validity of its certificate.	 It is almost always a bad idea	not to
	   check the certificates when transmitting confidential or important
	   data.  For self-signed/internal certificates, you should download
	   the certificate and verify against that instead of forcing this
	   insecure mode.  If you are really sure of not desiring any
	   certificate verification, you can specify --check-certificate=quiet
	   to tell wget	to not print any warning about invalid certificates,
	   albeit in most cases	this is	the wrong thing	to do.

       --certificate=file
	   Use the client certificate stored in	file.  This is needed for
	   servers that	are configured to require certificates from the
	   clients that	connect	to them.  Normally a certificate is not
	   required and	this switch is optional.

       --certificate-type=type
	   Specify the type of the client certificate.	Legal values are PEM
	   (assumed by default)	and DER, also known as ASN1.

       --private-key=file
	   Read	the private key	from file.  This allows	you to provide the
	   private key in a file separate from the certificate.

       --private-key-type=type
	   Specify the type of the private key.	 Accepted values are PEM (the
	   default) and	DER.

       --ca-certificate=file
	   Use file as the file	with the bundle	of certificate authorities
	   ("CA") to verify the	peers.	The certificates must be in PEM
	   format.

	   Without this	option Wget looks for CA certificates at the system-
	   specified locations,	chosen at OpenSSL installation time.

       --ca-directory=directory
	   Specifies directory containing CA certificates in PEM format.  Each
	   file	contains one CA	certificate, and the file name is based	on a
	   hash	value derived from the certificate.  This is achieved by
	   processing a	certificate directory with the "c_rehash" utility
	   supplied with OpenSSL.  Using --ca-directory	is more	efficient than
	   --ca-certificate when many certificates are installed because it
	   allows Wget to fetch	certificates on	demand.

	   Without this	option Wget looks for CA certificates at the system-
	   specified locations,	chosen at OpenSSL installation time.

       --crl-file=file
	   Specifies a CRL file	in file.  This is needed for certificates that
	   have	been revocated by the CAs.

       --pinnedpubkey=file/hashes
	   Tells wget to use the specified public key file (or hashes) to
	   verify the peer.  This can be a path	to a file which	contains a
	   single public key in	PEM or DER format, or any number of base64
	   encoded sha256 hashes preceded by "sha256//"	and separated by ";"

	   When	negotiating a TLS or SSL connection, the server	sends a
	   certificate indicating its identity.	A public key is	extracted from
	   this	certificate and	if it does not exactly match the public	key(s)
	   provided to this option, wget will abort the	connection before
	   sending or receiving	any data.

       --random-file=file
	   [OpenSSL and	LibreSSL only] Use file	as the source of random	data
	   for seeding the pseudo-random number	generator on systems without
	   /dev/urandom.

	   On such systems the SSL library needs an external source of
	   randomness to initialize.  Randomness may be	provided by EGD	(see
	   --egd-file below) or	read from an external source specified by the
	   user.  If this option is not	specified, Wget	looks for random data
	   in $RANDFILE	or, if that is unset, in $HOME/.rnd.

	   If you're getting the "Could	not seed OpenSSL PRNG; disabling SSL."
	   error, you should provide random data using some of the methods
	   described above.

       --egd-file=file
	   [OpenSSL only] Use file as the EGD socket.  EGD stands for Entropy
	   Gathering Daemon, a user-space program that collects	data from
	   various unpredictable system	sources	and makes it available to
	   other programs that might need it.  Encryption software, such as
	   the SSL library, needs sources of non-repeating randomness to seed
	   the random number generator used to produce cryptographically
	   strong keys.

	   OpenSSL allows the user to specify his own source of	entropy	using
	   the "RAND_FILE" environment variable.  If this variable is unset,
	   or if the specified file does not produce enough randomness,
	   OpenSSL will	read random data from EGD socket specified using this
	   option.

	   If this option is not specified (and	the equivalent startup command
	   is not used), EGD is	never contacted.  EGD is not needed on modern
	   Unix	systems	that support /dev/urandom.

       --no-hsts
	   Wget	supports HSTS (HTTP Strict Transport Security, RFC 6797) by
	   default.  Use --no-hsts to make Wget	act as a non-HSTS-compliant
	   UA. As a consequence, Wget would ignore all the
	   "Strict-Transport-Security" headers,	and would not enforce any
	   existing HSTS policy.

       --hsts-file=file
	   By default, Wget stores its HSTS database in	~/.wget-hsts.  You can
	   use --hsts-file to override this. Wget will use the supplied	file
	   as the HSTS database. Such file must	conform	to the correct HSTS
	   database format used	by Wget. If Wget cannot	parse the provided
	   file, the behaviour is unspecified.

	   The Wget's HSTS database is a plain text file. Each line contains
	   an HSTS entry (ie. a	site that has issued a
	   "Strict-Transport-Security" header and that therefore has specified
	   a concrete HSTS policy to be	applied). Lines	starting with a	dash
	   ("#") are ignored by	Wget. Please note that in spite	of this
	   convenient human-readability	hand-hacking the HSTS database is
	   generally not a good	idea.

	   An HSTS entry line consists of several fields separated by one or
	   more	whitespace:

	   "<hostname> SP [<port>] SP <include subdomains> SP <created>	SP
	   <max-age>"

	   The hostname	and port fields	indicate the hostname and port to
	   which the given HSTS	policy applies.	The port field may be zero,
	   and it will,	in most	of the cases. That means that the port number
	   will	not be taken into account when deciding	whether	such HSTS
	   policy should be applied on a given request (only the hostname will
	   be evaluated). When port is different to zero, both the target
	   hostname and	the port will be evaluated and the HSTS	policy will
	   only	be applied if both of them match. This feature has been
	   included for	testing/development purposes only.  The	Wget testsuite
	   (in testenv/) creates HSTS databases	with explicit ports with the
	   purpose of ensuring Wget's correct behaviour. Applying HSTS
	   policies to ports other than	the default ones is discouraged	by RFC
	   6797	(see Appendix B	"Differences between HSTS Policy and Same-
	   Origin Policy"). Thus, this functionality should not	be used	in
	   production environments and port will typically be zero. The	last
	   three fields	do what	they are expected to. The field
	   include_subdomains can either be 1 or 0 and it signals whether the
	   subdomains of the target domain should be part of the given HSTS
	   policy as well. The created and max-age fields hold the timestamp
	   values of when such entry was created (first	seen by	Wget) and the
	   HSTS-defined	value 'max-age', which states how long should that
	   HSTS	policy remain active, measured in seconds elapsed since	the
	   timestamp stored in created.	Once that time has passed, that	HSTS
	   policy will no longer be valid and will eventually be removed from
	   the database.

	   If you supply your own HSTS database	via --hsts-file, be aware that
	   Wget	may modify the provided	file if	any change occurs between the
	   HSTS	policies requested by the remote servers and those in the
	   file. When Wget exists, it effectively updates the HSTS database by
	   rewriting the database file with the	new entries.

	   If the supplied file	does not exist,	Wget will create one. This
	   file	will contain the new HSTS entries. If no HSTS entries were
	   generated (no "Strict-Transport-Security" headers were sent by any
	   of the servers) then	no file	will be	created, not even an empty
	   one.	This behaviour applies to the default database file
	   (~/.wget-hsts) as well: it will not be created until	some server
	   enforces an HSTS policy.

	   Care	is taken not to	override possible changes made by other	Wget
	   processes at	the same time over the HSTS database. Before dumping
	   the updated HSTS entries on the file, Wget will re-read it and
	   merge the changes.

	   Using a custom HSTS database	and/or modifying an existing one is
	   discouraged.	 For more information about the	potential security
	   threats arised from such practice, see section 14 "Security
	   Considerations" of RFC 6797,	specially section 14.9 "Creative
	   Manipulation	of HSTS	Policy Store".

       --warc-file=file
	   Use file as the destination WARC file.

       --warc-header=string
	   Use string into as the warcinfo record.

       --warc-max-size=size
	   Set the maximum size	of the WARC files to size.

       --warc-cdx
	   Write CDX index files.

       --warc-dedup=file
	   Do not store	records	listed in this CDX file.

       --no-warc-compression
	   Do not compress WARC	files with GZIP.

       --no-warc-digests
	   Do not calculate SHA1 digests.

       --no-warc-keep-log
	   Do not store	the log	file in	a WARC record.

       --warc-tempdir=dir
	   Specify the location	for temporary files created by the WARC
	   writer.

   FTP Options
       --ftp-user=user
       --ftp-password=password
	   Specify the username	user and password password on an FTP server.
	   Without this, or the	corresponding startup option, the password
	   defaults to -wget@, normally	used for anonymous FTP.

	   Another way to specify username and password	is in the URL itself.
	   Either method reveals your password to anyone who bothers to	run
	   "ps".  To prevent the passwords from	being seen, store them in
	   .wgetrc or .netrc, and make sure to protect those files from	other
	   users with "chmod".	If the passwords are really important, do not
	   leave them lying in those files either---edit the files and delete
	   them	after Wget has started the download.

       --no-remove-listing
	   Don't remove	the temporary .listing files generated by FTP
	   retrievals.	Normally, these	files contain the raw directory
	   listings received from FTP servers.	Not removing them can be
	   useful for debugging	purposes, or when you want to be able to
	   easily check	on the contents	of remote server directories (e.g. to
	   verify that a mirror	you're running is complete).

	   Note	that even though Wget writes to	a known	filename for this
	   file, this is not a security	hole in	the scenario of	a user making
	   .listing a symbolic link to /etc/passwd or something	and asking
	   "root" to run Wget in his or	her directory.	Depending on the
	   options used, either	Wget will refuse to write to .listing, making
	   the globbing/recursion/time-stamping	operation fail,	or the
	   symbolic link will be deleted and replaced with the actual .listing
	   file, or the	listing	will be	written	to a .listing.number file.

	   Even	though this situation isn't a problem, though, "root" should
	   never run Wget in a non-trusted user's directory.  A	user could do
	   something as	simple as linking index.html to	/etc/passwd and	asking
	   "root" to run Wget with -N or -r so the file	will be	overwritten.

       --no-glob
	   Turn	off FTP	globbing.  Globbing refers to the use of shell-like
	   special characters (wildcards), like	*, ?, [	and ] to retrieve more
	   than	one file from the same directory at once, like:

		   wget	ftp://gnjilux.srk.fer.hr/*.msg

	   By default, globbing	will be	turned on if the URL contains a
	   globbing character.	This option may	be used	to turn	globbing on or
	   off permanently.

	   You may have	to quote the URL to protect it from being expanded by
	   your	shell.	Globbing makes Wget look for a directory listing,
	   which is system-specific.  This is why it currently works only with
	   Unix	FTP servers (and the ones emulating Unix "ls" output).

       --no-passive-ftp
	   Disable the use of the passive FTP transfer mode.  Passive FTP
	   mandates that the client connect to the server to establish the
	   data	connection rather than the other way around.

	   If the machine is connected to the Internet directly, both passive
	   and active FTP should work equally well.  Behind most firewall and
	   NAT configurations passive FTP has a	better chance of working.
	   However, in some rare firewall configurations, active FTP actually
	   works when passive FTP doesn't.  If you suspect this	to be the
	   case, use this option, or set "passive_ftp=off" in your init	file.

       --preserve-permissions
	   Preserve remote file	permissions instead of permissions set by
	   umask.

       --retr-symlinks
	   By default, when retrieving FTP directories recursively and a
	   symbolic link is encountered, the symbolic link is traversed	and
	   the pointed-to files	are retrieved.	Currently, Wget	does not
	   traverse symbolic links to directories to download them
	   recursively,	though this feature may	be added in the	future.

	   When	--retr-symlinks=no is specified, the linked-to file is not
	   downloaded.	Instead, a matching symbolic link is created on	the
	   local filesystem.  The pointed-to file will not be retrieved	unless
	   this	recursive retrieval would have encountered it separately and
	   downloaded it anyway.  This option poses a security risk where a
	   malicious FTP Server	may cause Wget to write	to files outside of
	   the intended	directories through a specially	crafted	.LISTING file.

	   Note	that when retrieving a file (not a directory) because it was
	   specified on	the command-line, rather than because it was recursed
	   to, this option has no effect.  Symbolic links are always traversed
	   in this case.

   FTPS	Options
       --ftps-implicit
	   This	option tells Wget to use FTPS implicitly. Implicit FTPS
	   consists of initializing SSL/TLS from the very beginning of the
	   control connection. This option does	not send an "AUTH TLS"
	   command: it assumes the server speaks FTPS and directly starts an
	   SSL/TLS connection. If the attempt is successful, the session
	   continues just like regular FTPS ("PBSZ" and	"PROT" are sent,
	   etc.).  Implicit FTPS is no longer a	requirement for	FTPS
	   implementations, and	thus many servers may not support it. If
	   --ftps-implicit is passed and no explicit port number specified,
	   the default port for	implicit FTPS, 990, will be used, instead of
	   the default port for	the "normal" (explicit)	FTPS which is the same
	   as that of FTP, 21.

       --no-ftps-resume-ssl
	   Do not resume the SSL/TLS session in	the data channel. When
	   starting a data connection, Wget tries to resume the	SSL/TLS
	   session previously started in the control connection.  SSL/TLS
	   session resumption avoids performing	an entirely new	handshake by
	   reusing the SSL/TLS parameters of a previous	session. Typically,
	   the FTPS servers want it that way, so Wget does this	by default.
	   Under rare circumstances however, one might want to start an
	   entirely new	SSL/TLS	session	in every data connection.  This	is
	   what	--no-ftps-resume-ssl is	for.

       --ftps-clear-data-connection
	   All the data	connections will be in plain text. Only	the control
	   connection will be under SSL/TLS. Wget will send a "PROT C" command
	   to achieve this, which must be approved by the server.

       --ftps-fallback-to-ftp
	   Fall	back to	FTP if FTPS is not supported by	the target server. For
	   security reasons, this option is not	asserted by default. The
	   default behaviour is	to exit	with an	error.	If a server does not
	   successfully	reply to the initial "AUTH TLS"	command, or in the
	   case	of implicit FTPS, if the initial SSL/TLS connection attempt is
	   rejected, it	is considered that such	server does not	support	FTPS.

   Recursive Retrieval Options
       -r
       --recursive
	   Turn	on recursive retrieving.    The	default	maximum	depth is 5.

       -l depth
       --level=depth
	   Specify recursion maximum depth level depth.

       --delete-after
	   This	option tells Wget to delete every single file it downloads,
	   after having	done so.  It is	useful for pre-fetching	popular	pages
	   through a proxy, e.g.:

		   wget	-r -nd --delete-after http://whatever.com/~popular/page/

	   The -r option is to retrieve	recursively, and -nd to	not create
	   directories.

	   Note	that --delete-after deletes files on the local machine.	 It
	   does	not issue the DELE command to remote FTP sites,	for instance.
	   Also	note that when --delete-after is specified, --convert-links is
	   ignored, so .orig files are simply not created in the first place.

       -k
       --convert-links
	   After the download is complete, convert the links in	the document
	   to make them	suitable for local viewing.  This affects not only the
	   visible hyperlinks, but any part of the document that links to
	   external content, such as embedded images, links to style sheets,
	   hyperlinks to non-HTML content, etc.

	   Each	link will be changed in	one of the two ways:

	   o   The links to files that have been downloaded by Wget will be
	       changed to refer	to the file they point to as a relative	link.

	       Example:	if the downloaded file /foo/doc.html links to
	       /bar/img.gif, also downloaded, then the link in doc.html	will
	       be modified to point to ../bar/img.gif.	This kind of
	       transformation works reliably for arbitrary combinations	of
	       directories.

	   o   The links to files that have not	been downloaded	by Wget	will
	       be changed to include host name and absolute path of the
	       location	they point to.

	       Example:	if the downloaded file /foo/doc.html links to
	       /bar/img.gif (or	to ../bar/img.gif), then the link in doc.html
	       will be modified	to point to http://hostname/bar/img.gif.

	   Because of this, local browsing works reliably: if a	linked file
	   was downloaded, the link will refer to its local name; if it	was
	   not downloaded, the link will refer to its full Internet address
	   rather than presenting a broken link.  The fact that	the former
	   links are converted to relative links ensures that you can move the
	   downloaded hierarchy	to another directory.

	   Note	that only at the end of	the download can Wget know which links
	   have	been downloaded.  Because of that, the work done by -k will be
	   performed at	the end	of all the downloads.

       --convert-file-only
	   This	option converts	only the filename part of the URLs, leaving
	   the rest of the URLs	untouched. This	filename part is sometimes
	   referred to as the "basename", although we avoid that term here in
	   order not to	cause confusion.

	   It works particularly well in conjunction with --adjust-extension,
	   although this coupling is not enforced. It proves useful to
	   populate Internet caches with files downloaded from different
	   hosts.

	   Example: if some link points	to //foo.com/bar.cgi?xyz with
	   --adjust-extension asserted and its local destination is intended
	   to be ./foo.com/bar.cgi?xyz.css, then the link would	be converted
	   to //foo.com/bar.cgi?xyz.css. Note that only	the filename part has
	   been	modified. The rest of the URL has been left untouched,
	   including the net path ("//") which would otherwise be processed by
	   Wget	and converted to the effective scheme (ie. "http://").

       -K
       --backup-converted
	   When	converting a file, back	up the original	version	with a .orig
	   suffix.  Affects the	behavior of -N.

       -m
       --mirror
	   Turn	on options suitable for	mirroring.  This option	turns on
	   recursion and time-stamping,	sets infinite recursion	depth and
	   keeps FTP directory listings.  It is	currently equivalent to	-r -N
	   -l inf --no-remove-listing.

       -p
       --page-requisites
	   This	option causes Wget to download all the files that are
	   necessary to	properly display a given HTML page.  This includes
	   such	things as inlined images, sounds, and referenced stylesheets.

	   Ordinarily, when downloading	a single HTML page, any	requisite
	   documents that may be needed	to display it properly are not
	   downloaded.	Using -r together with -l can help, but	since Wget
	   does	not ordinarily distinguish between external and	inlined
	   documents, one is generally left with "leaf documents" that are
	   missing their requisites.

	   For instance, say document 1.html contains an "<IMG>" tag
	   referencing 1.gif and an "<A>" tag pointing to external document
	   2.html.  Say	that 2.html is similar but that	its image is 2.gif and
	   it links to 3.html.	Say this continues up to some arbitrarily high
	   number.

	   If one executes the command:

		   wget	-r -l 2	http://<site>/1.html

	   then	1.html,	1.gif, 2.html, 2.gif, and 3.html will be downloaded.
	   As you can see, 3.html is without its requisite 3.gif because Wget
	   is simply counting the number of hops (up to	2) away	from 1.html in
	   order to determine where to stop the	recursion.  However, with this
	   command:

		   wget	-r -l 2	-p http://<site>/1.html

	   all the above files and 3.html's requisite 3.gif will be
	   downloaded.	Similarly,

		   wget	-r -l 1	-p http://<site>/1.html

	   will	cause 1.html, 1.gif, 2.html, and 2.gif to be downloaded.  One
	   might think that:

		   wget	-r -l 0	-p http://<site>/1.html

	   would download just 1.html and 1.gif, but unfortunately this	is not
	   the case, because -l	0 is equivalent	to -l inf---that is, infinite
	   recursion.  To download a single HTML page (or a handful of them,
	   all specified on the	command-line or	in a -i	URL input file)	and
	   its (or their) requisites, simply leave off -r and -l:

		   wget	-p http://<site>/1.html

	   Note	that Wget will behave as if -r had been	specified, but only
	   that	single page and	its requisites will be downloaded.  Links from
	   that	page to	external documents will	not be followed.  Actually, to
	   download a single page and all its requisites (even if they exist
	   on separate websites), and make sure	the lot	displays properly
	   locally, this author	likes to use a few options in addition to -p:

		   wget	-E -H -k -K -p http://<site>/<document>

	   To finish off this topic, it's worth	knowing	that Wget's idea of an
	   external document link is any URL specified in an "<A>" tag,	an
	   "<AREA>" tag, or a "<LINK>" tag other than "<LINK
	   REL="stylesheet">".

       --strict-comments
	   Turn	on strict parsing of HTML comments.  The default is to
	   terminate comments at the first occurrence of -->.

	   According to	specifications,	HTML comments are expressed as SGML
	   declarations.  Declaration is special markup	that begins with <!
	   and ends with >, such as <!DOCTYPE ...>, that may contain comments
	   between a pair of --	delimiters.  HTML comments are "empty
	   declarations", SGML declarations without any	non-comment text.
	   Therefore, <!--foo--> is a valid comment, and so is <!--one--
	   --two-->, but <!--1--2--> is	not.

	   On the other	hand, most HTML	writers	don't perceive comments	as
	   anything other than text delimited with <!--	and -->, which is not
	   quite the same.  For	example, something like	<!------------>	works
	   as a	valid comment as long as the number of dashes is a multiple of
	   four	(!).  If not, the comment technically lasts until the next --,
	   which may be	at the other end of the	document.  Because of this,
	   many	popular	browsers completely ignore the specification and
	   implement what users	have come to expect: comments delimited	with
	   <!--	and -->.

	   Until version 1.9, Wget interpreted comments	strictly, which
	   resulted in missing links in	many web pages that displayed fine in
	   browsers, but had the misfortune of containing non-compliant
	   comments.  Beginning	with version 1.9, Wget has joined the ranks of
	   clients that	implements "naive" comments, terminating each comment
	   at the first	occurrence of -->.

	   If, for whatever reason, you	want strict comment parsing, use this
	   option to turn it on.

   Recursive Accept/Reject Options
       -A acclist --accept acclist
       -R rejlist --reject rejlist
	   Specify comma-separated lists of file name suffixes or patterns to
	   accept or reject. Note that if any of the wildcard characters, *,
	   ?, [	or ], appear in	an element of acclist or rejlist, it will be
	   treated as a	pattern, rather	than a suffix.	In this	case, you have
	   to enclose the pattern into quotes to prevent your shell from
	   expanding it, like in -A "*.mp3" or -A '*.mp3'.

       --accept-regex urlregex
       --reject-regex urlregex
	   Specify a regular expression	to accept or reject the	complete URL.

       --regex-type regextype
	   Specify the regular expression type.	 Possible types	are posix or
	   pcre.  Note that to be able to use pcre type, wget has to be
	   compiled with libpcre support.

       -D domain-list
       --domains=domain-list
	   Set domains to be followed.	domain-list is a comma-separated list
	   of domains.	Note that it does not turn on -H.

       --exclude-domains domain-list
	   Specify the domains that are	not to be followed.

       --follow-ftp
	   Follow FTP links from HTML documents.  Without this option, Wget
	   will	ignore all the FTP links.

       --follow-tags=list
	   Wget	has an internal	table of HTML tag / attribute pairs that it
	   considers when looking for linked documents during a	recursive
	   retrieval.  If a user wants only a subset of	those tags to be
	   considered, however,	he or she should be specify such tags in a
	   comma-separated list	with this option.

       --ignore-tags=list
	   This	is the opposite	of the --follow-tags option.  To skip certain
	   HTML	tags when recursively looking for documents to download,
	   specify them	in a comma-separated list.

	   In the past,	this option was	the best bet for downloading a single
	   page	and its	requisites, using a command-line like:

		   wget	--ignore-tags=a,area -H	-k -K -r http://<site>/<document>

	   However, the	author of this option came across a page with tags
	   like	"<LINK REL="home" HREF="/">" and came to the realization that
	   specifying tags to ignore was not enough.  One can't	just tell Wget
	   to ignore "<LINK>", because then stylesheets	will not be
	   downloaded.	Now the	best bet for downloading a single page and its
	   requisites is the dedicated --page-requisites option.

       --ignore-case
	   Ignore case when matching files and directories.  This influences
	   the behavior	of -R, -A, -I, and -X options, as well as globbing
	   implemented when downloading	from FTP sites.	 For example, with
	   this	option,	-A "*.txt" will	match file1.txt, but also file2.TXT,
	   file3.TxT, and so on.  The quotes in	the example are	to prevent the
	   shell from expanding	the pattern.

       -H
       --span-hosts
	   Enable spanning across hosts	when doing recursive retrieving.

       -L
       --relative
	   Follow relative links only.	Useful for retrieving a	specific home
	   page	without	any distractions, not even those from the same hosts.

       -I list
       --include-directories=list
	   Specify a comma-separated list of directories you wish to follow
	   when	downloading.  Elements of list may contain wildcards.

       -X list
       --exclude-directories=list
	   Specify a comma-separated list of directories you wish to exclude
	   from	download.  Elements of list may	contain	wildcards.

       -np
       --no-parent
	   Do not ever ascend to the parent directory when retrieving
	   recursively.	 This is a useful option, since	it guarantees that
	   only	the files below	a certain hierarchy will be downloaded.

ENVIRONMENT
       Wget supports proxies for both HTTP and FTP retrievals.	The standard
       way to specify proxy location, which Wget recognizes, is	using the
       following environment variables:

       http_proxy
       https_proxy
	   If set, the http_proxy and https_proxy variables should contain the
	   URLs	of the proxies for HTTP	and HTTPS connections respectively.

       ftp_proxy
	   This	variable should	contain	the URL	of the proxy for FTP
	   connections.	 It is quite common that http_proxy and	ftp_proxy are
	   set to the same URL.

       no_proxy
	   This	variable should	contain	a comma-separated list of domain
	   extensions proxy should not be used for.  For instance, if the
	   value of no_proxy is	.mit.edu, proxy	will not be used to retrieve
	   documents from MIT.

EXIT STATUS
       Wget may	return one of several error codes if it	encounters problems.

       0   No problems occurred.

       1   Generic error code.

       2   Parse error---for instance, when parsing command-line options, the
	   .wgetrc or .netrc...

       3   File	I/O error.

       4   Network failure.

       5   SSL verification failure.

       6   Username/password authentication failure.

       7   Protocol errors.

       8   Server issued an error response.

       With the	exceptions of 0	and 1, the lower-numbered exit codes take
       precedence over higher-numbered ones, when multiple types of errors are
       encountered.

       In versions of Wget prior to 1.12, Wget's exit status tended to be
       unhelpful and inconsistent. Recursive downloads would virtually always
       return 0	(success), regardless of any issues encountered, and non-
       recursive fetches only returned the status corresponding	to the most
       recently-attempted download.

FILES
       /usr/local/etc/wgetrc
	   Default location of the global startup file.

       .wgetrc
	   User	startup	file.

BUGS
       You are welcome to submit bug reports via the GNU Wget bug tracker (see
       <https://savannah.gnu.org/bugs/?func=additem&group=wget>).

       Before actually submitting a bug	report,	please try to follow a few
       simple guidelines.

       1.  Please try to ascertain that	the behavior you see really is a bug.
	   If Wget crashes, it's a bug.	 If Wget does not behave as
	   documented, it's a bug.  If things work strange, but	you are	not
	   sure	about the way they are supposed	to work, it might well be a
	   bug,	but you	might want to double-check the documentation and the
	   mailing lists.

       2.  Try to repeat the bug in as simple circumstances as possible.  E.g.
	   if Wget crashes while downloading wget -rl0 -kKE -t5	--no-proxy
	   http://example.com -o /tmp/log, you should try to see if the	crash
	   is repeatable, and if will occur with a simpler set of options.
	   You might even try to start the download at the page	where the
	   crash occurred to see if that page somehow triggered	the crash.

	   Also, while I will probably be interested to	know the contents of
	   your	.wgetrc	file, just dumping it into the debug message is
	   probably a bad idea.	 Instead, you should first try to see if the
	   bug repeats with .wgetrc moved out of the way.  Only	if it turns
	   out that .wgetrc settings affect the	bug, mail me the relevant
	   parts of the	file.

       3.  Please start	Wget with -d option and	send us	the resulting output
	   (or relevant	parts thereof).	 If Wget was compiled without debug
	   support, recompile it---it is much easier to	trace bugs with	debug
	   support on.

	   Note: please	make sure to remove any	potentially sensitive
	   information from the	debug log before sending it to the bug
	   address.  The "-d" won't go out of its way to collect sensitive
	   information,	but the	log will contain a fairly complete transcript
	   of Wget's communication with	the server, which may include
	   passwords and pieces	of downloaded data.  Since the bug address is
	   publically archived,	you may	assume that all	bug reports are
	   visible to the public.

       4.  If Wget has crashed,	try to run it in a debugger, e.g. "gdb `which
	   wget` core" and type	"where"	to get the backtrace.  This may	not
	   work	if the system administrator has	disabled core files, but it is
	   safe	to try.

       This is not the complete	manual for GNU Wget.  For more complete
       information, including more detailed explanations of some of the
       options,	and a number of	commands available for use with	.wgetrc	files
       and the -e option, see the GNU Info entry for wget.
