NAMEdpkg-trigger - a package trigger utility
SYNOPSISdpkg-trigger [option...] trigger-name
dpkg-trigger [option...] command
DESCRIPTIONdpkg-trigger is a tool to explicitely activate triggers and check for its support on the running dpkg.
This can be used by maintainer scripts in complex and conditional situations where the file triggers, or the declarative activate triggers control file directive, are insufficiently rich. It can also be used for testing and by system administrators (but note that the triggers won't actually be run by dpkg-trigger).
- Check if the running dpkg supports triggers (usually called from a postinst). Will exit 0 if a triggers-capable dpkg has run, or 1 with an error message to stderr if not. Normally, however, it is better just to activate the desired trigger with dpkg-trigger.
- -h, --help
- Show the usage message and exit.
- Show the version and exit.
- --license, --licence
- Show the copyright licensing terms and exit.
- Change the location of the dpkg database. The default location is /var/lib/dpkg.
- Override trigger awaiter (normally set by dpkg through the DPKG_MAINTSCRIPT_PACKAGE environment variable of the maintainer scripts, naming the package to which the script belongs, and this will be used by default).
- This option arranges that the calling package T (if any) need not await the processing of this trigger; the interested package(s) I, will not be added to T's trigger processing awaited list and T's status is unchanged. T may be considered installed even though I may not yet have processed the trigger.
- Just test, do not actually change anything.
