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



−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 the contents of all DWARF .dwo sections, leaving
    the remaining debugging sections and all symbols intact.
    See the description of this option in the objcopy
    section for more information.

    Remove all symbols that are not needed for relocation

−K symbolname

    When stripping symbols, keep symbol symbolname even if
    it would normally be stripped.  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 existing file.  When this argument is used, only one
    objfile argument may be specified.



    Preserve the access and modification dates of the file.


    Operate in deterministic mode.  When copying archive
    members and writing the archive index, use zero for
    UIDs, GIDs, timestamps, and use consistent file modes
    for all files.

    If binutils was configured with
    −−enable−deterministic−archives, then this mode is on by
    default.  It can be disabled with the −U option, below.


    Do not operate in deterministic mode.  This is the
    inverse of the −D option, above: when copying archive
    members and writing the archive index, use their actual
    UID, GID, timestamp, and file mode values.

    This is the default unless binutils was configured with


    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 ..)


    When stripping a file, perhaps with −−strip−debug or
    −−strip−unneeded, retain any symbols specifying source
    file names, which would otherwise get stripped.

    Strip a file, removing contents of any sections that
    would not be stripped by −−strip−debug and leaving the
    debugging sections intact.  In ELF files, this preserves
    all note sections in the output.

    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
        "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">

        i.e., 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.

        Note−−−this switch is only intended for use on fully
        linked files.  It does not make sense to use it on
        object files where the debugging information may be
        incomplete.  Besides the gnu_debuglink feature


        currently only supports the presence of one filename
        containing debugging information, not multiple
        filenames on a one‐per‐object‐file basis.

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

    Read command‐line options from file.  The options read
    are inserted in place of the original @file option.  If
    file does not exist, or cannot be read, then the option
    will be treated literally, and not removed.

    Options in file are separated by whitespace.  A
    whitespace character may be included in an option by
    surrounding the entire option in either single or double
    quotes.  Any character (including a backslash) may be
    included by prefixing the character to be included with
    a backslash.  The file may itself contain additional
    @file options; any such options will be processed
