Update ELF header and program property of ELF files.

SYNOPSIS

Header "SYNOPSIS" elfedit [ --input -mach= machine ] [ --input -type= type ] [ --input -osabi= osabi ] --output -mach= machine --output -type= type --output -osabi= osabi --enable -x86 -feature= feature --disable -x86 -feature= feature [ -v | --version ] [ -h | --help ] elffile ...

DESCRIPTION

Header "DESCRIPTION" elfedit updates the ELFheader and program property of ELF files which have the matching ELFmachine and file types. The options control how and which fields in the ELFheader and program property should be updated.

elffile ...are the ELFfiles to be updated. 32 -bit and 64 -bit ELFfiles are supported, as are archives containing ELFfiles.

OPTIONS

Header "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 , --enable -x86 -feature and --disable -x86 -feature options must be given.

" --input -mach= machine "4 Item "--input-mach=machine" Set the matching input ELFmachine type to machine .If --input -mach isn't specified, it will match any ELF machine types. The supported ELFmachine types are, i386 , IAMCU , L1OM , K1OM and x86-64 .

" --output -mach= machine "4 Item "--output-mach=machine" Change the ELFmachine type in the ELFheader to machine .The supported ELFmachine types are the same as --input -mach .

" --input -type= type "4 Item "--input-type=type" Set the matching input ELFfile type to type .If --input -type isn't specified, it will match any ELFfile types. The supported ELFfile types are, rel , exec and dyn .

" --output -type= type "4 Item "--output-type=type" Change the ELFfile type in the ELFheader to type .The supported ELFtypes are the same as --input -type .

" --input -osabi= osabi "4 Item "--input-osabi=osabi" Set the matching input ELFfile OSABIto osabi .If --input -osabi isn't specified, it will match any ELFOSABIs. The supported ELFOSABIs are, none , HPUX , NetBSD , GNU , Linux (alias for GNU ), Solaris , AIX , Irix , FreeBSD , TRU64 , Modesto , OpenBSD , OpenVMS , NSK , AROS and FenixOS .

" --output -osabi= osabi "4 Item "--output-osabi=osabi" Change the ELFOSABI in the ELFheader to osabi .The supported ELFOSABI are the same as --input -osabi .

" --enable -x86 -feature= feature "4 Item "--enable-x86-feature=feature" Set the feature bit in program property in exec or dyn ELFfiles with machine types of i386 or x86-64 .The supported features are, ibt and shstk .

" --disable -x86 -feature= feature "4 Item "--disable-x86-feature=feature" Clear the feature bit in program property in exec or dyn ELFfiles 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 "4 Item "-v" 0

" --version "4 Item "--version" Display the version number of elfedit .

" -h "4 Item "-h" 0

" --help "4 Item "--help" Display the command-line options understood by elfedit .

" @ file "4 Item "@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.
