        [--input-osabi=osabi]
        --output-mach=machine
        --output-type=type
        --output-osabi=osabi

DESCRIPTION

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

elffile... are the

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