elfedit - update ELF header and program property of ELF files 
Synopsis
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... 
Description
\&elfedit updates the \s-1ELF\s0 header and program property of \s-1ELF\s0 files which have the matching \s-1ELF\s0 machine and file types.  The options control how and which fields in the \s-1ELF\s0 header and program property should be updated. 
\&elffile... are the \s-1ELF\s0 files to be updated.  32-bit and 64-bit \s-1ELF\s0 files are supported, as are archives containing \s-1ELF\s0 files. 
Options
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. 
Set the matching input \s-1ELF\s0 machine type to machine.  If \&--input-mach isn't specified, it will match any \s-1ELF\s0 machine types. The supported \s-1ELF\s0 machine types are, i386, \s-1IAMCU\s0, L1OM, \&K1OM and x86-64. 
Change the \s-1ELF\s0 machine type in the \s-1ELF\s0 header to machine.  The supported \s-1ELF\s0 machine types are the same as --input-mach. 
Set the matching input \s-1ELF\s0 file type to type.  If \&--input-type isn't specified, it will match any \s-1ELF\s0 file types. The supported \s-1ELF\s0 file types are, rel, exec and dyn. 
Change the \s-1ELF\s0 file type in the \s-1ELF\s0 header to type.  The supported \s-1ELF\s0 types are the same as --input-type. 
Set the matching input \s-1ELF\s0 file \s-1OSABI\s0 to osabi.  If \&--input-osabi isn't specified, it will match any \s-1ELF\s0 OSABIs. The supported \s-1ELF\s0 OSABIs are, none, \s-1HPUX\s0, NetBSD, \&\s-1GNU\s0, Linux (alias for \s-1GNU\s0), \&Solaris, \s-1AIX\s0, Irix, \&FreeBSD, \s-1TRU64\s0, Modesto, OpenBSD, OpenVMS, \&\s-1NSK\s0, \s-1AROS\s0 and FenixOS. 
Change the \s-1ELF OSABI\s0 in the \s-1ELF\s0 header to osabi.  The supported \s-1ELF OSABI\s0 are the same as --input-osabi. 
Set the matching input \s-1ELF\s0 file \s-1ABIVERSION\s0 to version. \&version must be between 0 and 255.  If --input-abiversion isn't specified, it will match any \s-1ELF\s0 ABIVERSIONs. 
Change the \s-1ELF ABIVERSION\s0 in the \s-1ELF\s0 header to version. \&version must be between 0 and 255. 
Set the feature bit in program property in exec or dyn \&\s-1ELF\s0 files with machine types of i386 or x86-64.  The supported features are, ibt, shstk, lam_u48 and \&lam_u57. 
Clear the feature bit in program property in exec or \&dyn \s-1ELF\s0 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.
