SYNOPSIS
sa-update [options]
Options:
--channel channel Retrieve updates from this channel
Use multiple times for multiple channels
--channelfile file Retrieve updates from the channels in the file
--checkonly Check for update availability, do not install

DESCRIPTION
sa-update automates the process of downloading and installing new rules
and configuration, based on channels. The default channel is
updates.spamassassin.org, which has updated rules since the previous
release.
Update archives are verified using SHA256 and SHA512 hashes and GPG
signatures, by default.
Note that "sa-update" will not restart "spamd" or otherwise cause a
scanner to reload the now-updated ruleset automatically. Instead,
"sa-update" is typically used in something like the following manner:
sa-update && /etc/init.d/spamassassin reload
This works because "sa-update" only returns an exit status of 0 if it
has successfully downloaded and installed an updated ruleset.
The program sa-update uses the underlying operating system umask for
the updated rule files it installs. You may wish to run sa-update from
a script that sets the umask prior to calling sa-update. For example:
#!/bin/sh
umask 022
sa-update
OPTIONS
--channel
sa-update can update multiple channels at the same time. By
default, it will only access "updates.spamassassin.org", but more
channels can be specified via this option. If there are multiple
additional channels, use the option multiple times, once per
channel. i.e.:
sa-update --channel foo.example.com --channel bar.example.com
--channelfile
Similar to the --channel option, except specify the additional
channels in a file instead of on the commandline. This is useful
when there are a lot of additional channels.
--checkonly
Only check if an update is available, don't actually download and
install it. The exit code will be 0 or 1 as described below.
--install
Install updates "offline", from the named tar.gz file, instead of
performing DNS lookups and HTTP invocations.
Files named file.sha256, file.sha512, and file.asc will be used for
the SHA256 and SHA512 hashes and the GPG signature, respectively.
The filename provided must contain a version number of at least 3
digits, which will be used as the channel's update version number.
Multiple --channel switches cannot be used with --install. To
install multiple channels from tarballs, run "sa-update" multiple
times with different --channel and --install switches, e.g.:
sa-update --channel foo.example.com --install foo-34958.tgz
sa-update --channel bar.example.com --install bar-938455.tgz
--allowplugins
Allow downloaded updates to activate plugins. The default is not
to activate plugins; any "loadplugin" or "tryplugin" lines will be
commented in the downloaded update rules files.
You should never enable this for 3rd party update channels, since
plugins can execute unrestricted code on your system, even possibly
as root! This includes spamassassin official updates, which have no
need to include running code.
Use --reallyallowplugins option to bypass warnings and make it
work.
--gpg, --nogpg
sa-update by default will verify update archives by use of SHA256
and SHA512 checksums and GPG signature. SHA* hashes can verify
whether or not the downloaded archive has been corrupted, but it
does not offer any form of security regarding whether or not the
downloaded archive is legitimate (aka: non-modifed by evildoers).
GPG verification of the archive is used to solve that problem.
If you wish to skip GPG verification, you can use the --nogpg
option to disable its use. Use of the following gpgkey-related
options will override --nogpg and keep GPG verification enabled.
Note: Currently, only GPG itself is supported (ie: not PGP). v1.2
has been tested, although later versions ought to work as well.
--gpgkey
sa-update has the concept of "release trusted" GPG keys. When an
archive is downloaded and the signature verified, sa-update
requires that the signature be from one of these "release trusted"
keys or else verification fails. This prevents third parties from
manipulating the files on a mirror, for instance, and signing with
their own key.
By default, sa-update trusts key ids "24F434CE" and "5244EC45",
which are the standard SpamAssassin release key and its sub-key.
Use this option to trust additional keys. See the --import option
for how to add keys to sa-update's keyring. For sa-update to use a
key it must be in sa-update's keyring and trusted.
For multiple keys, use the option multiple times. i.e.:
sa-update --gpgkey E580B363 --gpgkey 298BC7D0
Note: use of this option automatically enables GPG verification.
--gpgkeyfile
Similar to the --gpgkey option, except specify the additional keys
in a file instead of on the commandline. This is extremely useful
when there are a lot of additional keys that you wish to trust.
--gpghomedir
Specify a directory path to use as a storage area for the
"sa-update" GPG keyring. By default, this is
/etc/mail/spamassassin/sa-update-keys
--import
Use to import GPG key(s) from a file into the sa-update keyring
which is located in the directory specified by --gpghomedir.
Before using channels from third party sources, you should use this
option to import the GPG key(s) used by those channels. You must
still use the --gpgkey or --gpgkeyfile options above to get sa-
update to trust imported keys.
To import multiple keys, use the option multiple times. i.e.:
sa-update --import channel1-GPG.KEY --import channel2-GPG.KEY
Note: use of this option automatically enables GPG verification.
--refreshmirrors
Force the list of sa-update mirrors for each channel, stored in the
MIRRORED.BY file, to be updated. By default, the MIRRORED.BY file
will be cached for up to 7 days after each time it is downloaded.
--updatedir
By default, "sa-update" will use the system-wide rules update
directory:
/var/lib/spamassassin/3.004006
If the updates should be stored in another location, specify it
here.
Note that use of this option is not recommended; if you're just
using sa-update to download updated rulesets for a scanner, and sa-
update is placing updates in the wrong directory, you probably need
to rebuild SpamAssassin with different "Makefile.PL" arguments,
instead of overriding sa-update's runtime behaviour.
-D [area,...], --debug [area,...]
Produce debugging output. If no areas are listed, all debugging
information is printed. Diagnostic output can also be enabled for
each area individually; area is the area of the code to instrument.
For example, to produce diagnostic output on channel, gpg, and
http, use:
sa-update -D channel,gpg,http
For more information about which areas (also known as channels) are
available, please see the documentation at
<http://wiki.apache.org/spamassassin/DebugChannels>;.
-h, --help
Print help message and exit.
-V, --version
Print sa-update version and exit.
EXIT CODES
In absence of a --checkonly option, an exit code of 0 means: an update
was available, and was downloaded and installed successfully. If
--checkonly was specified, an exit code of 0 means: an update was
available.
An exit code of 1 means no fresh updates were available.
An exit code of 2 means that at least one update is available but that
a lint check of the site pre files failed. The site pre files must
pass a lint check before any updates are attempted.
An exit code of 3 means that at least one update succeeded while other
channels failed. If using sa-compile, you should proceed with it.
An exit code of 4 or higher, indicates that errors occurred while
attempting to download and extract updates, and no channels were
updated.
