     elfedit - Update the ELF header of ELF files.

     elfedit [--input-mach=machine]

     elfedit updates the ELF header of ELF files which have the
     matching ELF machine and file types.  The options control
     how and which fields in the ELF header should be updated.

     elffile... are the ELF files to be updated.  32-bit and
     64-bit ELF files are supported, as are archives containing
     ELF files.

     The long and short forms of options, shown here as
     alternatives, are equivalent. At least one of the
     --output-mach, --output-type and --output-osabi options must
     be given.

         Set the matching input ELF machine type to machine.  If
         --input-mach isn't specified, it will match any ELF
         machine types.

         The supported ELF machine types are, L1OM, K1OM and

         Change the ELF machine type in the ELF header to
         machine.  The supported ELF machine types are the same
         as --input-mach.

         Set the matching input ELF file type to type.  If
         --input-type isn't specified, it will match any ELF file

         The supported ELF file types are, rel, exec and dyn.

         Change the ELF file type in the ELF header to type.  The
         supported ELF types are the same as --input-type.

         Set the matching input ELF file OSABI to osabi.  If
         --input-osabi isn't specified, it will match any ELF

         The supported ELF OSABIs are, none, HPUX, NetBSD, GNU,
         Linux (alias for GNU), Solaris, AIX, Irix, FreeBSD,
         TRU64, Modesto, OpenBSD, OpenVMS, NSK, AROS and FenixOS.

         Change the ELF OSABI in the ELF header to osabi.  The
         supported ELF OSABI are the same as --input-osabi.

         Display the version number of elfedit.

         Display the command line options understood by elfedit.

         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
