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.

       --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.

       --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 otherwise specified by --checks or freshclam.conf.

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

       -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 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-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 something 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       --on-outdated-execute=COMMAND
	      Execute COMMAND when freshclam reports outdated version.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.

       --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):SubmitDetectionStats for more details). No database  update
	      will be performed. This option only works in the interactive mode.

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

       --enable-stats
	      Enable submission of statistical data.

       --stats-host-id=UUID
	      HostID in the form of an UUID to use when submitting statistical information.

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.

       52: Connection (network) problem.

       54: MD5 or digital signature verification error.
