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 '' 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 --on-outdated-execute=COMMAND Execute COMMAND when freshclam reports outdated version.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. 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 RETURN CODES
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 is up-to-date or successfully updated. 40: Unknown option passed. 50: Can't change directory. 51: Can't check MD5 sum. 52: Connection (network) problem. 53: Can't unlink file. 54: MD5 or digital signature verification error. 55: Error reading file. 56: Config file error. 57: Can't create new file. 58: Can't read database from remote server. 59: Mirrors are not fully synchronized (try again later). 60: Can't get information about '' user from /etc/passwd. 61: Can't drop privileges. 62: Can't initialize logger.
