libalpm provides the ability to specify hooks to run before or after
transactions based on the packages and/or files being modified. Hooks consist
of a single [Action] section describing the action to be run and one or
more [Trigger] section describing which transactions it should be run
Hooks are read from files located in the system hook directory
/usr/share/libalpm/hooks, and additional custom directories specified in
pacman.conf(5) (the default is /etc/pacman.d/hooks). The file names
are required to have the suffix ".hook". Hooks are run in
alphabetical order of their file name, where the ordering ignores the
Hooks must contain at least one [Trigger] section that determines which
transactions will cause the hook to run. If multiple trigger sections are
defined the hook will run if the transaction matches any of the
Operation = Install|Upgrade|Remove
Select the type of operation to match targets against.
May be specified multiple times. Installations are considered an upgrade if
the package or file is already present on the system regardless of whether the
new package version is actually greater than the currently installed version.
For Path triggers, this is true even if the file changes ownership from one
package to another. Required.
Type = Path|Package
Select whether targets are matched against transaction
packages or files. See CAVEATS for special notes regarding Path triggers.
File is a deprecated alias for Path and will be removed in a
future release. Required.
Target = <path|package>
The path or package name to match against the active
transaction. Paths refer to the files in the package archive; the installation
root should not be included in the path. Shell-style glob patterns are
allowed. It is possible to invert matches by prepending a target with an
exclamation mark. May be specified multiple times. Required.
Description = ...
An optional description that describes the action being
taken by the hook for use in front-end output.
Exec = <command>
Command to run. Command arguments are split on
whitespace. Values containing whitespace should be enclosed in quotes.
When = PreTransaction|PostTransaction
When to run the hook. Required.
Depends = <package>
Packages that must be installed for the hook to run. May
be specified multiple times.
Causes the transaction to be aborted if the hook exits
non-zero. Only applies to PreTransaction hooks.
Causes the list of matched trigger targets to be passed
to the running hook on stdin.
Hooks may be overridden by placing a file with the same name in a higher
priority hook directory. Hooks may be disabled by overriding them with a
symlink to /dev/null.
There are situations when path triggers may act in unexpected ways. Hooks are
triggered using the file list of the installed, upgraded, or removed package.
When installing or upgrading a file that is extracted with a .pacnew
extension, the original file name is used in triggering the hook. When
removing a package, all files owned by that package can trigger a hook whether
or not they were actually present on the file system before package removal.
# Force disks to sync to reduce the risk of data corruption
Operation = Install
Operation = Upgrade
Operation = Remove
Type = Package
Target = *
Depends = coreutils
When = PostTransaction
Exec = /usr/bin/sync
PostTransaction hooks will not run if the transaction fails
to complete for any reason.

Bugs? You must be kidding; there are no bugs in this software. But if we happen
to be wrong, submit a bug report with as much detail as possible at the Arch
Linux Bug Tracker in the Pacman section.
