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

33 The long and short forms of options, shown here as alternatives, are
34 equivalent. At least one of the --output-mach, --output-type,
35 --output-osabi, --output-abiversion, --enable-x86-feature and
36 --disable-x86-feature options must be given.
37 --input-mach=machine
39 Set the matching input ELF machine type to machine. If
40 --input-mach isn't specified, it will match any ELF machine types.
41 The supported ELF machine types are, i386, IAMCU, L1OM, K1OM and
43 x86-64.
44 --output-mach=machine
46 Change the ELF machine type in the ELF header to machine. The
47 supported ELF machine types are the same as --input-mach.
48 --input-type=type
50 Set the matching input ELF file type to type. If --input-type
51 isn't specified, it will match any ELF file types.
52 The supported ELF file types are, rel, exec and dyn.
54 --output-type=type
56 Change the ELF file type in the ELF header to type. The supported
57 ELF types are the same as --input-type.
58 --input-osabi=osabi
60 Set the matching input ELF file OSABI to osabi. If --input-osabi
61 isn't specified, it will match any ELF OSABIs.
62 The supported ELF OSABIs are, none, HPUX, NetBSD, GNU, Linux (alias
64 for GNU), Solaris, AIX, Irix, FreeBSD, TRU64, Modesto, OpenBSD,
65 OpenVMS, NSK, AROS and FenixOS.
66 --output-osabi=osabi
68 Change the ELF OSABI in the ELF header to osabi. The supported ELF
69 OSABI are the same as --input-osabi.
70 --input-abiversion=version
72 Set the matching input ELF file ABIVERSION to version. version
73 must be between 0 and 255. If --input-abiversion isn't specified,
74 it will match any ELF ABIVERSIONs.
75 --output-abiversion=version
77 Change the ELF ABIVERSION in the ELF header to version. version
78 must be between 0 and 255.
79 --enable-x86-feature=feature
81 Set the feature bit in program property in exec or dyn ELF files
82 with machine types of i386 or x86-64. The supported features are,
83 ibt, shstk, lam_u48 and lam_u57.
84 --disable-x86-feature=feature
86 Clear the feature bit in program property in exec or dyn ELF files
87 with machine types of i386 or x86-64. The supported features are
88 the same as --enable-x86-feature.
89 Note: --enable-x86-feature and --disable-x86-feature are available
91 only on hosts with mmap support.
92 -v
94 --version
95 Display the version number of elfedit.
96 -h
98 --help
99 Display the command-line options understood by elfedit.
100 @file
102 Read command-line options from file. The options read are inserted
103 in place of the original @file option. If file does not exist, or
104 cannot be read, then the option will be treated literally, and not
105 removed.
106 Options in file are separated by whitespace. A whitespace
108 character may be included in an option by surrounding the entire
109 option in either single or double quotes. Any character (including
110 a backslash) may be included by prefixing the character to be
111 included with a backslash. The file may itself contain additional
112 @file options; any such options will be processed recursively.
