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 'clamav' 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 'clamav' 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--on-outdated-execute=COMMAND

Execute COMMAND when freshclam reports outdated version.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
