READELF(1) General Commands Manual READELF(1) NAME readelf -- display information about ELF objects SYNOPSIS readelf [-a | --all] [-c | --archive-index] [-d | --dynamic] [-e | --headers] [-g | --section-groups] [-h | --file-header] [-l | --program-headers] [-n | --notes] [-p section | --string-dump=section] [-r | --relocs] [-t | --section-details] [-u | --unwind] [-v | --version] [-w[afilmoprsFLR] | --debug-dump[=long-option-name,...]] [-x section | --hex-dump=section] [-z | --decompress] [-A | --arch-specific] [-D | --use-dynamic] [-H | --help] [-I | --histogram] [-N | --full-section-name] [-S | --sections | --section-headers] [-V | --version-info] [-W | --wide] file... DESCRIPTION The readelf utility displays information about ELF objects and ar(1) archives. The readelf utility recognizes the following options: -a | --all Turn on the following flags: -d, -h, -I, -l, -n, -r, -s, -u, -A, -S and -V. -c | --archive-index Print the archive symbol table for archives. -d | --dynamic Print the contents of the SHT_DYNAMIC sections in the ELF ob- ject. -e | --headers Print all program, file and section headers in the ELF object. -g | --section-groups Print the contents of the section groups in the ELF object. -h | --file-header Print the file header of the ELF object. -l | --program-headers Print the content of the program header table for the object. -n | --notes Print the contents of PT_NOTE segments or SHT_NOTE sections present in the ELF object. -p section | --string-dump=section Print the contents of the specified section as printable strings. The argument section should be the name of a section or a numeric section index. -r | --relocs Print relocation information. -s | --syms | --symbols Print symbol tables. -t | --section-details Print additional information about sections, such as the flags fields in section headers. Implies -S. -u | --unwind Not yet implemented (option accepted but ignored). -v | --version Prints a version identifier for readelf and exits. -w[afilmoprsFLR] | --debug-dump[=long-option-name,...] Display DWARF information. The -w option is used with the short options in the following table; the --debug-dump option is used with a comma-separated list of the corresponding long option names: Short Option Long Option Description a abbrev Show abbreviation information. f frames Show frame information, displaying frame instructions. i info Show debugging information entries. l rawline Show line information in raw form. m macro Show macro information. o loc Show location list information. p pubnames Show global names. r aranges|ranges Show address range information. s str Show the debug string table. F frames-interp Show frame information, displaying register rules. L decodedline Show line information in decoded form. R Ranges Show range lists. If no sub-options are specified, the default is to show infor- mation corresponding to the a, f, i, l, o, p, r, s and R short options. -x section | --hex-dump=section Display the contents of the specified section in hexadecimal. The argument section should be the name of a section or a nu- meric section index. -z | --decompress Decompress contents of sections specified by -x or -p before displaying. If the specified section is not compressed, it is displayed as is. -A | --arch-specific This option is accepted but is currently unimplemented. -D | --use-dynamic Print the symbol table specified by the DT_SYMTAB entry in the ".dynamic" section. -H | --help Print a help message. -I | --histogram Print information on bucket list lengths for sections of type SHT_HASH and SHT_GNU_HASH. -N | --full-section-name This option is accepted but is currently unimplemented. -S | --sections | --section-headers Print information in the section headers for each ELF object. -V | --version-info Print symbol versioning information. -W | --wide Print information about ELF structures using one long line per structure. If this option is not specified, readelf will list information in the headers of 64 bit ELF objects on two sepa- rate lines. EXIT STATUS The readelf utility exits 0 on success, and >0 if an error occurs.
