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.

--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.

-u USER, --user USER
Run as USER. By default (when started by root) freshclam drops privileges and
operates 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--on-outdated-execute=COMMAND
Execute COMMAND when freshclam reports outdated version.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.

--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.

--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
database names. This option can be used multiple times and only works with the
official and 3rd party databases distrubuted through the ClamAV mirrors, your
custom databases (specified with DatabaseCustomURL in freshclam.conf) will not be
ignored.

--enable-stats
Enable submission of statistical data.

--stats-host-id=UUID
HostID in the form of an UUID to use when submitting statistical information.

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.
