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 additional 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 oper-
	      ates 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 systems. 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 something 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       --on-outdated-execute=COMMAND
	      Execute COMMAND when freshclam reports outdated version.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 freshclam.conf(5):SubmitDe-
	      tectionStats for more details). No database update will be performed.  This  option
	      only works in the interactive 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 command EXIT_n which can
       be passed to --on-*-execute, eg. --on-update-execute=EXIT_1 will force freshclam to always
       return 1 after successful database update.

       0 : Database is up-to-date or successfully updated.

       40: Unknown option passed.

       50: Can't change directory.

       51: Can't check MD5 sum.
