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.

       --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/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/3.004002

           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.
