NAME

     elfedit - Update the ELF header of ELF files.

SYNOPSIS

     elfedit [--input-mach=machine]
             [--input-type=type]
             [--input-osabi=osabi]
             --output-mach=machine
             --output-type=type
             --output-osabi=osabi
             [-v|--version]
             [-h|--help]
             elffile...

DESCRIPTION

     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

     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.

     --input-mach=machine
         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, i386, IAMCU, L1OM,
         K1OM and x86-64.

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

     --input-type=type
         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.

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

     --input-osabi=osabi
         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.

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

     -v
     --version
         Display the version number of elfedit.

     -h
     --help
         Display the command line options understood by elfedit.

     @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.
