       elfedit - Update the ELF header of ELF files.

SYNOPSIS         top

       elfedit [--input-mach=machine]

DESCRIPTION         top

       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.

OPTIONS         top

       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

           The supported ELF machine types are, i386, IAMCU, 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 types.

           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 OSABIs.

           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 recursively.
