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
            archives, strip -v lists all members of the archive.
