3 deb\-triggers \- package triggers
9 A package declares its relationship to some trigger(s) by including
10 a \fItriggers\fP file in its control archive (i.e. \fIDEBIAN/triggers\fP
11 during package creation).
13 This file contains directives, one per line. Leading and trailing whitespace
14 and everything after the first \fB#\fP on any line will be trimmed, and
15 empty lines will be ignored.
17 The trigger control directives currently supported are:
24 Specifies that the package is interested in the named trigger. All
25 triggers in which a package is interested must be listed using this
26 directive in the triggers control file.
33 Arranges that changes to this package's state will activate the
34 specified trigger. The trigger will be activated at the start of
35 the following operations: unpack, configure, remove (including for
36 the benefit of a conflicting package), purge and deconfigure.
39 If this package disappears during the unpacking of another package
40 the trigger will be activated when the disappearance is noted
41 towards the end of the unpack. Trigger processing, and transition
42 from triggers-awaited to installed, does not cause activations.
43 In the case of unpack, triggers mentioned in both the old and new
44 versions of the package will be activated.
46 Unknown directives are an error which will prevent installation of the
50 .BR dpkg\-trigger (1),
52 .BR /usr/share/doc/dpkg/triggers.txt.gz .
