23 libalpm provides the ability to specify hooks to run before or after
24 transactions based on the packages and/or files being modified. Hooks
25 consist of a single [Action] section describing the action to be run
26 and one or more [Trigger] section describing which transactions it
27 should be run for. Hook file names are required to have the suffix
28 ".hook". Hooks are run in alphabetical order of their file name.
29
31 Hooks must contain at least one [Trigger] section that determines which
32 transactions will cause the hook to run. If multiple trigger sections
33 are defined the hook will run if the transaction matches any of the
34 triggers.
35 Operation = Install|Upgrade|Remove
37 Select the type of operation to match targets against. May be
38 specified multiple times. Installations are considered an upgrade
39 if the package or file is already present on the system regardless
40 of whether the new package version is actually greater than the
41 currently installed version. For File triggers, this is true even
42 if the file changes ownership from one package to another.
43 Required.
44 Type = File|Package
46 Select whether targets are matched against transaction packages or
47 files. See CAVEATS for special notes regarding File triggers.
48 Required.
49 Target = <path|package>
51 The file path or package name to match against the active
52 transaction. File paths refer to the files in the package archive;
53 the installation root should not be included in the path.
54 Shell-style glob patterns are allowed. It is possible to invert
55 matches by prepending a file with an exclamation mark. May be
56 specified multiple times. Required.
57
59 Description = ...
60 An optional description that describes the action being taken by
61 the hook for use in front-end output.
62 Exec = <command>
64 Command to run. Command arguments are split on whitespace. Values
65 containing whitespace should be enclosed in quotes. Required.
66 When = PreTransaction|PostTransaction
68 When to run the hook. Required.
69 Depends = <package>
71 Packages that must be installed for the hook to run. May be
72 specified multiple times.
73 AbortOnFail
75 Causes the transaction to be aborted if the hook exits non-zero.
76 Only applies to PreTransaction hooks.
77 NeedsTargets
79 Causes the list of matched trigger targets to be passed to the
80 running hook on stdin.
81
83 Hooks may be overridden by placing a file with the same name in a
84 higher priority hook directory. Hooks may be disabled by overriding
85 them with a symlink to /dev/null.
86
88 # Force disks to sync to reduce the risk of data corruption
89 [Trigger]
91 Operation = Install
92 Operation = Upgrade
93 Operation = Remove
94 Type = Package
95 Target = *
96 [Action]
98 Depends = coreutils
99 When = PostTransaction
100 Exec = /usr/bin/sync
101
103 There are situations when file triggers may act in unexpected ways.
104 Hooks are triggered using the file list of the installed, upgraded, or
105 removed package. When installing or upgrading a file that is extracted
106 with a .pacnew extension, the original file name is used in triggering
107 the hook. When removing a package, all files owned by that package can
108 trigger a hook whether or not they were actually present on the file
109 system before package removal.
110 PostTransaction hooks will not run if the transaction fails to complete
112 for any reason.

118 Bugs? You must be kidding; there are no bugs in this software. But if
119 we happen to be wrong, send us an email with as much detail as possible
