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	avail-
	   able.

       -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-unneeded
	   Remove all symbols that are not needed for relocation processing.

       -K symbolname
       --keep-symbol=symbolname
	   Keep	 only symbol symbolname	from the source	file.  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.

       -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 sym-
	   bol	name.  If the first character of the symbol name is the	excla-
	   mation 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	..)

       --only-keep-debug
	   Strip  a  file,  removing  any  sections  that would	be stripped by
	   --strip-debug and leaving the debugging sections.

	   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  dis-
	   tribution and the second a debugging	information file which is only
	   needed if debugging abilities are required.	The  suggested	proce-
	   dure	to create these	files is as follows:

	   1.<Link the executable as normal.  Assuming that is is called>
	       "foo" then...

	   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 exe-
	       cutable.

	   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">

	   ie 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.

       -V
       --version
	   Show	the version number for strip.

       -v
       --verbose
	   Verbose output: list	all object files modified.  In the case	of ar-
	   chives, strip -v lists all members of the archive.
