       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.

              Be quiet - output only error messages.

              Don't print and log warnings.

              Write all messages to stdout.

       -l FILE, --log=FILE
              Write download report to FILE.

              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.

              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.

              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.

              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.

              Execute COMMAND after successful update.

              Execute  COMMAND when freshclam reports outdated version.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

              Print mirror details from mirrors.dat (cache file for the mirror

              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:


       (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 is up-to-date or successfully updated.

       40: Unknown option passed.

       50: Can't change directory.

       56: Config file error.

       57: Can't create new file.

       58: Can't read database from remote server.
