dh_missing [-Xitem] [--sourcedir=dir] [debhelper options]
dh_missing compares the list of installed files with the files in the source directory. If any of the files (and symlinks) in the source directory were not installed to somewhere, it will warn on stderr about that (--list-missing) or fail (--fail-missing). Please note that without either of these options, dh_missing will silently do nothing.
This may be useful if you have a large package and want to make sure that you don't miss installing newly added files in new upstream releases.
Remember to test different kinds of builds (dpkg-buildpackage -A/-B/...) as you may experience varying results when only a subset of the packages are built.
dh_missing will expand wildcards in this file (since debhelper 11.1). Wildcards without matches will be ignored.
Note that files that are excluded from being moved via the -X option are not warned about.
This is the default in compat 12 and later.
This program is a part of debhelper.
