       GNU strip discards all symbols from object files objfile.  The list of
       object files may include archives.  At least one object file  must  be

       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.

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

       -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 unusable.

           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 once.

       -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 exist-
           ing 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 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''.

           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 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
           procedure to create these files is as follows:

               "foo" then...

               create a file containing the debugging info.

               stripped executable.

               to add a link to the debugging info  into  the  stripped  exe-

           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:


           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.
