DESCRIPTION
       readelf displays	information about one or more ELF format object	files.
       The options control what	particular information to display.

       elffile... are the object files to be examined.	32-bit and 64-bit ELF
       files are supported, as are archives containing ELF files.

       This program performs a similar function	to objdump but it goes into
       more detail and it exists independently of the BFD library, so if there
       is a bug	in BFD then readelf will not be	affected.

OPTIONS
       The long	and short forms	of options, shown here as alternatives,	are
       equivalent.  At least one option	besides	-v or -H must be given.

       -a
       --all
	   Equivalent to specifying --file-header, --program-headers,
	   --sections, --symbols, --relocs, --dynamic, --notes and
	   --version-info.

       -h
       --file-header
	   Displays the	information contained in the ELF header	at the start
	   of the file.

       -l
       --program-headers
       --segments
	   Displays the	information contained in the file's segment headers,
	   if it has any.

       -S
       --sections
       --section-headers
	   Displays the	information contained in the file's section headers,
	   if it has any.

       -g
       --section-groups
	   Displays the	information contained in the file's section groups, if
	   it has any.

       -t
       --section-details
	   Displays the	detailed section information. Implies -S.

       -s
       --symbols
       --syms
	   Displays the	entries	in symbol table	section	of the file, if	it has
	   one.

       --dyn-syms
	   Displays the	entries	in dynamic symbol table	section	of the file,
	   if it has one.

       -e
       --headers
	   Display all the headers in the file.	 Equivalent to -h -l -S.

       -n
       --notes
	   Displays the	contents of the	NOTE segments and/or sections, if any.

       -r
       --relocs
	   Displays the	contents of the	file's relocation section, if it has
	   one.

       -u
       --unwind
	   Displays the	contents of the	file's unwind section, if it has one.
	   Only	the unwind sections for	IA64 ELF files,	as well	as ARM unwind
	   tables (".ARM.exidx"	/ ".ARM.extab")	are currently supported.

       -d
       --dynamic
	   Displays the	contents of the	file's dynamic section,	if it has one.

       -V
       --version-info
	   Displays the	contents of the	version	sections in the	file, it they
	   exist.

       -A
       --arch-specific
	   Displays architecture-specific information in the file, if there is
	   any.

       -D
       --use-dynamic
	   When	displaying symbols, this option	makes readelf use the symbol
	   hash	tables in the file's dynamic section, rather than the symbol
	   table sections.

       -x <number or name>
       --hex-dump=<number or name>
	   Displays the	contents of the	indicated section as a hexadecimal
	   bytes.  A number identifies a particular section by index in	the
	   section table; any other string identifies all sections with	that
	   name	in the object file.

       -R <number or name>
       --relocated-dump=<number	or name>
	   Displays the	contents of the	indicated section as a hexadecimal
	   bytes.  A number identifies a particular section by index in	the
	   section table; any other string identifies all sections with	that
	   name	in the object file.  The contents of the section will be
	   relocated before they are displayed.

       -p <number or name>
       --string-dump=<number or	name>
	   Displays the	contents of the	indicated section as printable
	   strings.  A number identifies a particular section by index in the
	   section table; any other string identifies all sections with	that
	   name	in the object file.

       -c
       --archive-index
	   Displays the	file symbol index information contained	in the header
	   part	of binary archives.  Performs the same function	as the t
	   command to ar, but without using the	BFD library.

       -w[lLiaprmfFsoRt]
       --debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges,=pubtypes,=trace_info,=trace_abbrev,=trace_aranges,=gdb_index]
	   Displays the	contents of the	debug sections in the file, if any are
	   present.  If	one of the optional letters or words follows the
	   switch then only data found in those	specific sections will be
	   dumped.

	   Note	that there is no single	letter option to display the content
	   of trace sections or	.gdb_index.

	   Note: the =decodedline option will display the interpreted contents
	   of a	.debug_line section whereas the	=rawline option	dumps the
	   contents in a raw format.

	   Note: the =frames-interp option will	display	the interpreted
	   contents of a .debug_frame section whereas the =frames option dumps
	   the contents	in a raw format.

	   Note: the output from the =info option can also be affected by the
	   options --dwarf-depth and --dwarf-start.

       --dwarf-depth=n
	   Limit the dump of the ".debug_info" section to n children.  This is
	   only	useful with --debug-dump=info.	The default is to print	all
	   DIEs; the special value 0 for n will	also have this effect.

	   With	a non-zero value for n,	DIEs at	or deeper than n levels	will
	   not be printed.  The	range for n is zero-based.

       --dwarf-start=n
	   Print only DIEs beginning with the DIE numbered n.  This is only
	   useful with --debug-dump=info.

	   If specified, this option will suppress printing of any header
	   information and all DIEs before the DIE numbered n.	Only siblings
	   and children	of the specified DIE will be printed.

	   This	can be used in conjunction with	--dwarf-depth.

       -I
       --histogram
	   Display a histogram of bucket list lengths when displaying the
	   contents of the symbol tables.

       -v
       --version
	   Display the version number of readelf.

       -W
       --wide
	   Don't break output lines to fit into	80 columns. By default readelf
	   breaks section header and segment listing lines for 64-bit ELF
	   files, so that they fit into	80 columns. This option	causes readelf
	   to print each section header	resp. each segment one a single	line,
	   which is far	more readable on terminals wider than 80 columns.

       -H
       --help
	   Display the command line options understood by readelf.

       @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.
