freshclam − update virus databases
freshclam [options]
freshclam is a virus database update tool for ClamAV.
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−−on−outdated−execute=COMMAND
Execute COMMAND when freshclam reports outdated version.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.
(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
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 successfully updated.
1 : Database is up−to−date.
