NAME
       freshclam - update virus	databases

SYNOPSIS
       freshclam [options]

DESCRIPTION
       freshclam is a virus database update tool for ClamAV.

OPTIONS
       Freshclam reads its configuration from freshclam.conf. The settings can
       be overwritten with command line	options.

       -h, --help
	      Output help information and exit.

       -V, --version
	      Print version number and exit.

       -v, --verbose
	      Be verbose. This option causes freshclam	to  print  much	 addi-
	      tional information.

       --debug
	      Enable debug messages from LibClamAV.

       --quiet
	      Be quiet - output	only error messages.

       --no-warnings
	      Don't print and log warnings.

       --stdout
	      Write all	messages to stdout.

       --show-progress
	      Show download progress percentage.

       --config-file=FILE
	      Read configuration from FILE.

       -l FILE,	--log=FILE
	      Log report to FILE.

       -d, --daemon
	      Run  in a	daemon mode. Defaults to 12 checks per day unless oth-
	      erwise specified by --checks or freshclam.conf.

       -p FILE,	--pid=FILE
	      Write daemon's pid to FILE.

       -F, --foreground
	      Don't fork into background (for use in daemon mode).

       -u USER,	--user USER
	      Run as USER. By default (when started by root)  freshclam	 drops
	      privileges and operates as the ''	user.

       --no-dns
	      This  option  forces  old	non-DNS	verification method (without a
	      TTL delay).

       -c #n, --checks=#n
	      Check #n times per day for a new database. #n must be between  1
	      and 50.

       --datadir=DIRECTORY
	      Install  new  database  in  DIRECTORY.  The  directory  must  be
	      writable for the '' user or unprivileged user running freshclam.

       --daemon-notify=/path/to/clamd.conf
	      Notify the daemon	about the new database.	By default it reads  a
	      hardcoded	 config	file but you can use a different one. Both lo-
	      cal and TCP sockets are supported.

       -a IP, --local-address=IP
	      Use (local) IP for HTTP downloads. Useful	for  multi-homed  sys-
	      tems.  If	binding	fails for whatever reason, a warning is	issued
	      and freshclam behaves like without this flag.

       --on-update-execute=COMMAND
	      Execute COMMAND after successful update.

       --on-error-execute=COMMAND
	      Execute COMMAND if error occurred. Remember, that	virus database
	      freshness	is the most important thing in anti-virus system. With
	      this option freshclam can	alert you (eg. send  SMS)  when	 some-
	      thing is going wrong.

       --on-outdated-execute=COMMAND
	      Execute  COMMAND when freshclam reports outdated version.	In the
	      command string %v	will be	replaced by the	new version number.

       --update-db=DBNAME
	      With this	option you can limit updates to	a subset  of  database
	      files.   The  DBNAME  should  be	"main",	 "daily",  "bytecode",
	      "safebrowsing" or	one of the 3rd party database names. This  op-
	      tion can be used multiple	times and only works with the official
	      and 3rd party databases distributed through the ClamAV  mirrors,
	      your  custom  databases  (specified  with	 DatabaseCustomURL  in
	      freshclam.conf) will not be ignored.

EXAMPLES
       (0) Download database to	default	directory:

	      freshclam

       (1) Download database to	current	directory:

	      freshclam	--datadir=.

       (2) Run as a daemon and check 2 times per day for new database:

	      freshclam	-d -c 2

RETURN CODES
       Some return codes of freshclam can be overwritten with a	built-in  com-
       mand EXIT_n which can be	passed to --on-*-execute, eg. --on-update-exe-
       cute=EXIT_1 will	force freshclam	to always return  1  after  successful
       database	update.
