freshclam - update virus databases
freshclam [options]
freshclam updates the virus database. Its a part of the Clam AntiVirus package. It requires an Internet connection.
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 the standard output (stdout), instead of the standard error output (stderr). -l FILE, --log=FILE Save download report in 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 works as the clamav user. -d, --daemon Run in a daemon mode. This option requires --checks. -p FILE, --pid=FILE Save daemons pid in 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 an another 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 --on-outdated-execute=COMMAND Execute COMMAND when freshclam reports outdated version.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.
