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.

       --debug
              Enable debug messages from LibClamAV.

       --quiet
              Be quiet - output only error messages.

       --no-warnings
              Don't print and log warnings.

       --stdout
              Write all messages to stdout.

       --show-progress
              Show download progress percentage.

       --config-file=FILE
              Read configuration from FILE.

       -l FILE, --log=FILE
              Log report to FILE.

       -d, --daemon
              Run in a daemon mode. Defaults to 12 checks per day unless otherwise  specified  by
              --checks or freshclam.conf.

       -p FILE, --pid=FILE
              Write daemon's pid to FILE.

       -F, --foreground
              Don't fork into background (for use in daemon mode).

       -u USER, --user USER
              Run as USER. By default (when started by root) freshclam drops privileges and oper-
              ates as the '' user.

       --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.

       --datadir=DIRECTORY
              Install new database in DIRECTORY. The directory must be writable for the  ''  user
              or unprivileged user running freshclam.

       --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-update-execute=COMMAND
              Execute COMMAND after successful update.

       --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-outdated-execute=COMMAND
              Execute COMMAND when freshclam reports outdated version. In the command  string  %v
              will be replaced by the new version number.

       --update-db=DBNAME
              With  this  option  you can limit updates to a subset of database files. The DBNAME
              should be "main", "daily", "bytecode", "safebrowsing" or one of the 3rd party data-
              base names. This option can be used multiple times and only works with the official
              and 3rd party databases distributed through the ClamAV mirrors, your  custom  data-
              bases (specified with DatabaseCustomURL in freshclam.conf) will not be ignored.

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.

       54: MD5 or digital signature verification error.

       55: Error reading file.

       56: Config file error.

       57: Can't create new file.
