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.
