       strip - Discard symbols from object files.

	     [-I bfdname |--input-target=bfdname]
	     [-O bfdname |--output-target=bfdname]
	     [-K symbolname |--keep-symbol=symbolname]
	     [-N symbolname |--strip-symbol=symbolname]
	     [-x|--discard-all] [-X |--discard-locals]
	     [-R sectionname |--remove-section=sectionname]

	     [-v |--verbose] [-V|--version]
	     [--help] [--info]

       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.

       -F bfdname
	   Treat  the original objfile as a file with the object code format bfdname, and rewrite
	   it in the same format.

	   Show a summary of the options to strip and exit.

	   Display a list showing all architectures and object formats available.

       -I bfdname
	   Treat the original objfile as a file with the object code format bfdname.

       -O bfdname
	   Replace objfile with a file in the output format bfdname.

       -R 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

	   Remove all symbols.

	   Remove debugging symbols only.

	   Remove all symbols that are not needed for relocation processing.

       -K symbolname
	   Keep only symbol symbolname from the source file.  This option may be given more  than

       -N 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.

	   Preserve the access and modification dates of the file.

	   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

		     -w -K !foo -K fo*

	   would cause strip to only keep symbols that start with the letters ``fo'', but to dis-
	   card the symbol ``foo''.

	   Remove non-global symbols.

	   Remove compiler-generated local symbols.  (These usually start with L or ..)

	   Strip a file, removing any sections that would be stripped by --strip-debug and  leav-
	   ing 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 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:

	   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 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">

	   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.

	   Show the version number for strip.

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