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 addi‐
tional 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 sys‐
tems. 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 some‐
thing 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--on-outdated-execute=COMMAND
Execute COMMAND when freshclam reports outdated version.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 fresh‐
clam.conf(5):SubmitDetectionStats for more details). No database
update will be performed. This option only works in the interac‐
tive 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 com‐
mand EXIT_n which can be passed to --on-*-execute, eg. --on-update-exe‐
cute=EXIT_1 will force freshclam to always return 1 after successful
database update.

50: Can't change directory.
