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.

       --quiet
	      Be quiet - output only error messages.

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

       --stdout
	      Write all messages to stdout.

       -l FILE, --log=FILE
	      Write download report to FILE.

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

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

       -d, --daemon
	      Run  in  a daemon mode. This option requires --checks.  -p FILE,
	      --pid=FILE Write daemon's pid to FILE.

       --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.

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

       --on-outdated-execute=COMMAND
	      Execute  COMMAND when freshclam reports outdated version.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

       --list-mirrors
	      Print mirror details from mirrors.dat (cache file for the mirror
	      manager).

       --submit-stats[=/path/to/clamd.conf]
	      Upload  detection	 statistics  to the ClamAV Project (see fresh‐
	      clam.conf(5):SubmitDetectionStats for more details). No database
	      update will be performed. This option only works in the interac‐
	      tive mode.

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.

       40: Unknown option passed.

       50: Can't change directory.
