SYNOPSIS

       elfedit [--input-mach=machine]
               [--input-type=type]
               [--input-osabi=osbi]
               --output-mach=machine
               --output-type=type
               --output-osabi=osbi
               [-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, L1OM 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 osbi.  If --input-osabi isn't specified, it will  match  any
           ELF OSABIs.

           The  supported  ELF  OSABIs are, none, HPUX, NetBSD, Linux, Hurd, Solaris, AIX, Irix, FreeBSD, TRU64,
           Modesto, OpenBSD, OpenVMS, NSK, AROS and FenixOS.

       --output-osabi=osabi
           Change the ELF OSABI in  the  ELF  header  to  type.   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.
