elfedit - update ELF header and program property of ELF files
elfedit [--input-mach=machine]
[--input-type=type]
[--input-osabi=osabi]
[--input-abiversion=version]
--output-mach=machine
--output-type=type
--output-osabi=osabi
--output-abiversion=version
--enable-x86-feature=feature
--disable-x86-feature=feature
[-v|--version]
[-h|--help]
elffile...
elfedit updates the ELF header and program property of ELF files
which have the matching ELF machine and file types. The options
control how and which fields in the ELF header and program
property 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,
--output-osabi, --output-abiversion, --enable-x86-feature and
--disable-x86-feature 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.
--input-abiversion=version
Set the matching input ELF file ABIVERSION to version.
version must be between 0 and 255. If --input-abiversion
isn't specified, it will match any ELF ABIVERSIONs.
--output-abiversion=version
Change the ELF ABIVERSION in the ELF header to version.
version must be between 0 and 255.
--enable-x86-feature=feature
Set the feature bit in program property in exec or dyn ELF
files with machine types of i386 or x86-64. The supported
features are, ibt, shstk, lam_u48 and lam_u57.
--disable-x86-feature=feature
Clear the feature bit in program property in exec or dyn ELF
files with machine types of i386 or x86-64. The supported
features are the same as --enable-x86-feature.
Note: --enable-x86-feature and --disable-x86-feature are
available only on hosts with mmap support.
-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.
