Manual freshclam:
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 many additional informations.
--quiet
Be quiet - output only error messages.
--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--on-outdated-execute=COMMAND
Execute COMMAND when freshclam reports outdated version.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
Pring mirror details from mirrors.dat (cache file for the mirror manager).
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
