binutils-2.44                                      2025-03-21                                          RANLIB(1)

ranlib generates an index to the contents of an archive and stores it in the archive.  The index lists
       each symbol defined by a member of an archive that is a relocatable object file.

       You may use nm-s or nm--print-armap to list this index.

       An archive with such an index speeds up linking to the library and allows routines in the library to call
       each other without regard to their placement in the archive.

       The GNU ranlib program is another form of GNU ar; running ranlib is completely equivalent to executing ar-s.

-h-H--help
           Show usage information for ranlib.

       -v-V--version
           Show the version number of ranlib.

       -D  Operate  in  deterministic  mode.  The symbol map archive member's header will show zero for the UID,
           GID, and timestamp.  When this option is used, multiple runs will produce identical output files.

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

       -t  Update the timestamp of the symbol map of an archive.

       -U  Do not operate in deterministic mode.  This is the inverse of the -D option, above: the archive index
           will get actual UID, GID, timestamp, and file mode values.

           If binutils was configured without--enable-deterministic-archives, then this mode is on by default.

       @file
           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 recursively.
