elfedit - update ELF header and program property of ELF files
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
options must be given.
Set the matching input ELF machine type to machine. If
--input-mach isn't specified, it will match any ELF
The supported ELF machine types are, i386, IAMCU, L1OM,
K1OM and x86-64.
Change the ELF machine type in the ELF header to machine. The
supported ELF machine types are the same as --input-mach.
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.
Change the ELF file type in the ELF header to type. The
supported ELF types are the same as --input-type.
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.
Change the ELF OSABI in the ELF header to osabi. The
supported ELF OSABI are the same as --input-osabi.
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 and shstk.
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.
Display the version number of elfedit.
Display the command-line options understood by elfedit.
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.
