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.
-v, --debug
Enable debug messages from LibClamAV.
--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--on-outdated-execute=COMMAND
Execute COMMAND when freshclam reports outdated version.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
