dh - debhelper command sequencer
dh sequence [--with addon[,addon,...]] [--list] [--until cmd] [--before
cmd] [--after cmd] [--remaining] [debhelperoptions]
dh runs a sequence of debhelper commands. The supported sequences
correspond to the targets of a debian/rules file: "build", "clean",
"install", "binary-arch", "binary-indep", and "binary".
Commands in the binary-indep sequence are passed the "-i" option to
ensure they only work on binary independent packages, and commands in
the binary-arch sequences are passed the "-a" option to ensure they
only work on architecture dependent packages.
Each debhelper command will record when it’s successfully run in
debian/package.debhelper.log. (Which dh_clean deletes.) So dh can tell
which commands have already been run, for which packages, and skip
running those commands again.
Each time dh is run, it examines the log, and finds the last logged
command that is in the specified sequence. It then continues with the
next command in the sequence. The --until, --before, --after, and
--remaining options can override this behavior.
If debian/rules contains a target with a name like
"override_dh_command", then when it would normally run dh_command, dh
will instead call that target. The override target can then run the
command with additional options, or run entirely different commands
instead. See examples below. (Note that to use this feature, you should
Build-Depend on debhelper 7.0.50 or above.)
Add the debhelper commands specified by the given addon to
appropriate places in the sequence of commands that is run. This
option can be repeated more than once, or multiple addons can be
listed, separated by commas. This is used when there is a third-
party package that provides debhelper commands. See the PROGRAMMING
file for documentation about the sequence addon interface.
The inverse of --with, disables using the given addon.
List all available addons.
Run commands in the sequence until and including cmd, then stop.
Run commands in the sequence before cmd, then stop.
Run commands in the sequence that come after cmd.
Run all commands in the sequence that have yet to be run.
Prints commands that would run for a given sequence, but does not
All other options passed to dh are passed on to each command it runs.
This can be used to set an option like "-v" or "-X" or "-N", as well as
for more specialised options.
In the above options, cmd can be a full name of a debhelper command, or
a substring. It’ll first search for a command in the sequence exactly
matching the name, to avoid any ambiguity. If there are multiple
substring matches, the last one in the sequence will be used.
To see what commands are included in a sequence, without actually doing
dh binary-arch --no-act
This is a very simple rules file, for packages where the default
sequences of commands work with no additional options.
Often you’ll want to pass an option to a specific debhelper command.
The easy way to do with is by adding an override target for that

Sometimes the automated dh_auto_configure and dh_auto_build can’t guess
what to do for a strange package. Here’s how to avoid running either
and instead run your own commands.
Another common case is wanting to do something manually before or after
a particular debhelper command is run.
chmod 4755 debian/foo/usr/bin/foo
If your package is a python package, dh will use dh_pysupport by
default. This is how to use dh_pycentral instead.
dh $@ --with python-central
Here is how to force use of perl’s Module::Build build system, which
can be necessary if debhelper wrongly detects that the package uses
dh $@ --buildsystem=perl_build
To patch your package using quilt, you can tell dh to use quilt’s dh
sequence addons like this:
dh $@ --with quilt
Here is an example of overriding where the dh_auto_* commands find the
package’s source, for a package where the source is located in a
dh $@ --sourcedirectory=src
And here is an example of how to tell the dh_auto_* commands to build
in a subdirectory, which will be removed on clean.
dh $@ --builddirectory=build
Finally, here is a way to prevent dh from running several commands that
you don’t want it to run, by defining empty override targets for each
