    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-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 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 ..)
    --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 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.

    -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.
