dpkg-trigger(1)                             dpkg suite                            dpkg-trigger(1)

       dpkg-trigger - a package trigger utility

       dpkg-trigger [option...] trigger-name
       dpkg-trigger [option...] command

       dpkg-trigger  is  a  tool to explicitly 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 insuffi‐
       ciently 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).

       Unrecognized trigger name syntaxes are an error for 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

       -?, --help
              Show the usage message and exit.

              Show the version 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  pro‐
              cessing  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.

              This option does the inverse of --no-await. It is currently the default behavior.

              Just test, do not actually change anything.

              If  set  and  the  --admindir option has not been specified, it will be used as the
              dpkg data directory.
