NAME

       dh_strip - strip executables, shared libraries, and some static libraries

SYNOPSIS

       dh_strip [debhelper options] [-Xitem] [--dbg-package=package] [--keep-debug]

DESCRIPTION

       dh_strip is a debhelper program that is responsible for stripping executables, shared libraries, and
       static libraries that are not used for debugging.

       This program examines your package build directories and works out what to strip on its own. It uses
       file(1) and file permissions and filenames to figure out what files are shared libraries (*.so),
       executable binaries, and static (lib*.a) and debugging libraries (lib*_g.a, debug/*.so), and strips each
       as much as is possible. (Which is not at all for debugging libraries.) In general it seems to make very
       good guesses, and will do the right thing in almost all cases.

       Since it is very hard to automatically guess if a file is a module, and hard to determine how to strip a
       module, dh_strip does not currently deal with stripping binary modules such as .o files.

OPTIONS

       -Xitem, --exclude=item
           Exclude  files  that  contain  item  anywhere in their filename from being stripped. You may use this
           option multiple times to build up a list of things to exclude.

       --dbg-package=package
           This option is a now special purpose option that you normally do not  need.   In  most  cases,  there
           should  be  little  reason  to  use  this  option  for new source packages as debhelper automatically
           generates debug packages ("dbgsym packages").  If you have a manual --dbg-package that  you  want  to
           replace  with  an  automatically  generated  debug  symbol package, please see the --dbgsym-migration
           option.

           Causes dh_strip to save debug symbols stripped from the packages it acts on as independent  files  in
           the package build directory of the specified debugging package.

           For  example,  if  your  packages  are  libfoo and foo and you want to include a foo-dbg package with
           debugging symbols, use dh_strip --dbg-package=foo-dbg.

           Note that this option behaves significantly different in debhelper compatibility levels 4 and  below.
           Instead  of  specifying  the  name  of  a debug package to put symbols in, it specifies a package (or
           packages) which should have separated debug symbols, and the separated symbols are placed in packages
           with -dbg added to their name.

           This  option  implies  --no-automatic-dbgsym  and  cannot  be   used   with   --automatic-dbgsym   or
           --dbgsym-migration.

       -k, --keep-debug
           This  option  is  a  now  special purpose option that you normally do not need.  In most cases, there
           should be little reason to use this  option  for  new  source  packages  as  debhelper  automatically
           generates  debug  packages  ("dbgsym packages").  If you have a manual --dbg-package that you want to
           replace with an automatically generated debug  symbol  package,  please  see  the  --dbgsym-migration
           option.

           Debug  symbols  will be retained, but split into an independent file in usr/lib/debug/ in the package
           build directory. --dbg-package is easier to use than this option, but this option is more flexible.

           This option implies --no-automatic-dbgsym and cannot be used with --automatic-dbgsym.

       --dbgsym-migration=package-relation
           This option is used to migrate from a manual  "-dbg"  package  (created  with  --dbg-package)  to  an
           automatic  generated  debug  symbol  package.  This  option  should  describe  a  valid Replaces- and
           Breaks-relation, which will be added to the debug symbol package to avoid  file  conflicts  with  the
           (now obsolete) -dbg package.

           This  option  implies  --automatic-dbgsym  and  cannot  be  used  with --keep-debug, --dbg-package or
           --no-automatic-dbgsym.

           Examples:

             dh_strip --dbgsym-migration='libfoo-dbg (<< 2.1-3~)'

             dh_strip --dbgsym-migration='libfoo-tools-dbg (<< 2.1-3~), libfoo2-dbg (<< 2.1-3~)'

       --automatic-dbgsym, --no-automatic-dbgsym
           Control whether dh_strip should be creating debug symbol packages when possible.

           The default is to create debug symbol packages.

       --ddebs, --no-ddebs
           Historical name for --automatic-dbgsym and --no-automatic-dbgsym.

       --ddeb-migration=package-relation
           Historical name for --dbgsym-migration.

NOTES

       If the DEB_BUILD_OPTIONS environment variable contains nostrip, nothing will be stripped,  in  accordance
       with  Debian  policy  (section  10.1 "Binaries").  This will also inhibit the automatic creation of debug
       symbol packages.

       The automatic creation of debug symbol packages can also be  prevented  by  adding  noautodbgsym  to  the
       DEB_BUILD_OPTIONS environment variable.

CONFORMS TO

       Debian policy, version 3.0.1
