DESCRIPTION
GNU strip discards all symbols from object files objfile.
The list of object files may include archives. At least one
object file must be given.
strip modifies the files named in its argument, rather than
writing modified copies under different names.
OPTIONS
-F bfdname
--target=bfdname
Treat the original objfile as a file with the object
code format bfdname, and rewrite it in the same format.
--help
Show a summary of the options to strip and exit.
--info
Display a list showing all architectures and object
formats available.
-I bfdname
--input-target=bfdname
Treat the original objfile as a file with the object
code format bfdname.
-O bfdname
--output-target=bfdname
Replace objfile with a file in the output format

bfdname.
-R sectionname
--remove-section=sectionname
Remove any section named sectionname from the output
file. This option may be given more than once. Note
that using this option inappropriately may make the
output file unusable.
-s
--strip-all
Remove all symbols.
-g
-S
-d
--strip-debug
Remove debugging symbols only.
--strip-dwo
Remove the contents of all DWARF .dwo sections, leaving
the remaining debugging sections and all symbols intact.
See the description of this option in the objcopy
section for more information.
--strip-unneeded
Remove all symbols that are not needed for relocation
processing.
-K symbolname
--keep-symbol=symbolname
When stripping symbols, keep symbol symbolname even if
it would normally be stripped. This option may be given
more than once.
-N symbolname
--strip-symbol=symbolname
Remove symbol symbolname from the source file. This
option may be given more than once, and may be combined
with strip options other than -K.
-o file
Put the stripped output in file, rather than replacing
the existing file. When this argument is used, only one
objfile argument may be specified.
-p
--preserve-dates
Preserve the access and modification dates of the file.
-D
--enable-deterministic-archives
binutils-2.23.1 Last change: 2012-11-13 2
GNU Development Tools STRIP(1)
Operate in deterministic mode. When copying archive
members and writing the archive index, use zero for
UIDs, GIDs, timestamps, and use consistent file modes
for all files.
-w
--wildcard
Permit regular expressions in symbolnames used in other
command line options. The question mark (?), asterisk
(*), backslash (\) and square brackets ([]) operators
can be used anywhere in the symbol name. If the first
character of the symbol name is the exclamation point
(!) then the sense of the switch is reversed for that
symbol. For example:
-w -K !foo -K fo*
would cause strip to only keep symbols that start with
the letters "fo", but to discard the symbol "foo".
-x
--discard-all
Remove non-global symbols.
-X
--discard-locals
Remove compiler-generated local symbols. (These usually
start with L or ..)
--keep-file-symbols
When stripping a file, perhaps with --strip-debug or
--strip-unneeded, retain any symbols specifying source
file names, which would otherwise get stripped.
--only-keep-debug
Strip a file, removing contents of any sections that
would not be stripped by --strip-debug and leaving the
debugging sections intact. In ELF files, this preserves
all note sections in the output.
The intention is that this option will be used in
conjunction with --add-gnu-debuglink to create a two
part executable. One a stripped binary which will
occupy less space in RAM and in a distribution and the
second a debugging information file which is only needed
if debugging abilities are required. The suggested
procedure to create these files is as follows:
called>
1.<Link the executable as normal. Assuming that is is
"foo" then...
binutils-2.23.1 Last change: 2012-11-13 3
GNU Development Tools STRIP(1)
1.<Run "objcopy --only-keep-debug foo foo.dbg" to>
create a file containing the debugging info.
1.<Run "objcopy --strip-debug foo" to create a>
stripped executable.
1.<Run "objcopy --add-gnu-debuglink=foo.dbg foo">
to add a link to the debugging info into the
stripped executable.
Note---the choice of ".dbg" as an extension for the
debug info file is arbitrary. Also the
"--only-keep-debug" step is optional. You could instead
do this:
1.<Link the executable as normal.>
1.<Copy "foo" to "foo.full">
1.<Run "strip --strip-debug foo">
1.<Run "objcopy --add-gnu-debuglink=foo.full foo">
i.e., the file pointed to by the --add-gnu-debuglink can
be the full executable. It does not have to be a file
created by the --only-keep-debug switch.
Note---this switch is only intended for use on fully
linked files. It does not make sense to use it on
object files where the debugging information may be
incomplete. Besides the gnu_debuglink feature currently
only supports the presence of one filename containing
debugging information, not multiple filenames on a one-
per-object-file basis.
-V
--version
Show the version number for strip.
-v
--verbose
Verbose output: list all object files modified. In the
case of archives, strip -v lists all members of the
archive.
@file
Read command-line options from file. The options read
are inserted in place of the original @file option. If
file does not exist, or cannot be read, then the option
will be treated literally, and not removed.
Options in file are separated by whitespace. A
whitespace character may be included in an option by
surrounding the entire option in either single or double
quotes. Any character (including a backslash) may be
binutils-2.23.1 Last change: 2012-11-13 4
GNU Development Tools STRIP(1)
included by prefixing the character to be included with
a backslash. The file may itself contain additional
@file options; any such options will be processed
recursively.
