	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 object.
-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 information 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 numeric 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 separate lines.
