UNZIP(1)		FreeBSD	General	Commands Manual		      UNZIP(1)

NAME
     unzip -- extract files from a ZIP archive

SYNOPSIS
     unzip [-aCcfjLlnopqtuv] [-d dir] zipfile

DESCRIPTION
     The following options are available:

     -a		 When extracting a text	file, convert DOS-style	line endings
		 to Unix-style line endings.

     -C		 Match file names case-insensitively.

     -c		 Extract to stdout/screen.  When extracting files from the
		 zipfile, they are written to stdout.  This is similar to -p,
		 but doesn't suppress normal output.

     -d	dir	 Extract files into the	specified directory rather than	the
		 current directory.

     -f		 Update	existing.  Extract only	files from the zipfile if a
		 file with the same name already exists	on disk	and is older
		 than the former.  Otherwise, the file is silently skipped.

     -j		 Ignore	directories stored in the zipfile; instead, extract
		 all files directly into the extraction	directory.

     -L		 Convert the names of the extracted files and directories to
		 lowercase.

     -l		 List, rather than extract, the	contents of the	zipfile.

     -n		 No overwrite.	When extracting	a file from the	zipfile, if a
		 file with the same name already exists	on disk, the file is
		 silently skipped.

     -o		 Overwrite.  When extracting a file from the zipfile, if a
		 file with the same name already exists	on disk, the existing
		 file is replaced with the file	from the zipfile.

     -p		 Extract to stdout.  When extracting files from	the zipfile,
		 they are written to stdout.  The normal output	is suppressed
		 as if -q was specified.

     -q		 Quiet:	print less information while extracting.

     -t		 Test: do not extract anything,	but verify the checksum	of
		 every file in the archive.

     -u		 Update.  When extracting a file from the zipfile, if a	file
		 with the same name already exists on disk, the	existing file
		 is replaced with the file from	the zipfile if and only	if the
		 latter	is newer than the former.  Otherwise, the file is
		 silently skipped.

     -v		 List verbosely, rather	than extract, the contents of the zip-
		 file.	This differs from -l by	using the long listing.	 Note
		 that most of the data is currently fake and does not reflect
		 the content of	the archive.

     -x	pattern	 Exclude files matching	the pattern pattern.

     -Z	mode	 Emulate zipinfo(1L) mode.  Enabling zipinfo(1L) mode changes
		 the way in which additional arguments are parsed.  Currently
		 only zipinfo(1L) mode 1 is supported, which lists the file
		 names one per line.

     Note that only one	of -n, -o, and -u may be specified.  If	specified
     filename is "-", then data	is read	from stdin.

ENVIRONMENT
     If	the UNZIP_DEBUG	environment variable is	defined, the -q	command-line
     option has	no effect, and additional debugging information	will be
     printed to	stderr.

COMPATIBILITY
     The unzip utility aims to be sufficiently compatible with other implemen-
     tations to	serve as a drop-in replacement in the context of the ports(7)
     system.  No attempt has been made to replicate functionality which	is not
     required for that purpose.

     For compatibility reasons,	command-line options will be recognized	if
     they are listed not only before but also after the	name of	the zipfile.

     Normally, the -a option should only affect	files which are	marked as text
     files in the zipfile's central directory.	Since the archive(3) library
     reads zipfiles sequentially, and does not use the central directory, that
     information is not	available to the unzip utility.	 Instead, the unzip
     utility will assume that a	file is	a text file if no non-ASCII characters
     are present within	the first block	of data	decompressed for that file.
     If	non-ASCII characters appear in subsequent blocks of data, a warning
     will be issued.

     The unzip utility is only able to process ZIP archives handled by
     libarchive(3).  Depending on the installed	version	of libarchive, this
     may or may	not include self-extracting archives.

HISTORY
     The unzip utility appeared	in FreeBSD 8.0.
