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 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 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       --on-outdated-execute=COMMAND
	      Execute COMMAND when freshclam reports outdated version.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):SubmitDetectionStats 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.

       52: Connection (network) problem.

       53: Can't unlink file.

       54: MD5 or digital signature verification error.

       55: Error reading file.

       56: Config file error.

       57: Can't create new file.

       58: Can't read database from remote server.
