22 elfedit updates the ELF header and program property of ELF files which
23 have the matching ELF machine and file types. The options control how
24 and which fields in the ELF header and program property should be
25 updated.
26 elffile... are the ELF files to be updated. 32-bit and 64-bit ELF
28 files are supported, as are archives containing ELF files.

31 The long and short forms of options, shown here as alternatives, are
32 equivalent. At least one of the --output-mach, --output-type,
33 --output-osabi, --enable-x86-feature and --disable-x86-feature options
34 must be given.
35 --input-mach=machine
37 Set the matching input ELF machine type to machine. If
38 --input-mach isn't specified, it will match any ELF machine types.
39 The supported ELF machine types are, i386, IAMCU, L1OM, K1OM and
41 x86-64.
42 --output-mach=machine
44 Change the ELF machine type in the ELF header to machine. The
45 supported ELF machine types are the same as --input-mach.
46 --input-type=type
48 Set the matching input ELF file type to type. If --input-type
49 isn't specified, it will match any ELF file types.
50 The supported ELF file types are, rel, exec and dyn.
52 --output-type=type
54 Change the ELF file type in the ELF header to type. The supported
55 ELF types are the same as --input-type.
56 --input-osabi=osabi
58 Set the matching input ELF file OSABI to osabi. If --input-osabi
59 isn't specified, it will match any ELF OSABIs.
60 The supported ELF OSABIs are, none, HPUX, NetBSD, GNU, Linux (alias
62 for GNU), Solaris, AIX, Irix, FreeBSD, TRU64, Modesto, OpenBSD,
63 OpenVMS, NSK, AROS and FenixOS.
64 --output-osabi=osabi
66 Change the ELF OSABI in the ELF header to osabi. The supported ELF
67 OSABI are the same as --input-osabi.
68 --enable-x86-feature=feature
70 Set the feature bit in program property in exec or dyn ELF files
71 with machine types of i386 or x86-64. The supported features are,
72 ibt, shstk, lam_u48 and lam_u57.
73 --disable-x86-feature=feature
75 Clear the feature bit in program property in exec or dyn ELF files
76 with machine types of i386 or x86-64. The supported features are
77 the same as --enable-x86-feature.
78 Note: --enable-x86-feature and --disable-x86-feature are available
80 only on hosts with mmap support.
81 -v
83 --version
84 Display the version number of elfedit.
85 -h
87 --help
88 Display the command-line options understood by elfedit.
89 @file
91 Read command-line options from file. The options read are inserted
92 in place of the original @file option. If file does not exist, or
93 cannot be read, then the option will be treated literally, and not
94 removed.
95 Options in file are separated by whitespace. A whitespace
97 character may be included in an option by surrounding the entire
98 option in either single or double quotes. Any character (including
99 a backslash) may be included by prefixing the character to be
100 included with a backslash. The file may itself contain additional
101 @file options; any such options will be processed recursively.
