       readelf [-a|--all]
	       [-h|--file-header]
	       [-l|--program-headers|--segments]
	       [-S|--section-headers|--sections]

	       [-V|--version-info]
	       [-D|--use-dynamic]
	       [-x <number>|--hex-dump=<number>]
	       [-w[liaprmfFso]|--debug-dump[=line,=info,=abbrev,=pub-
       names,=ranges,=macro,=frames,=str,=loc]]

	       elffile...

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.	At the moment, readelf
       does not	support	examining archives, nor	does it	support	 examining  64
       bit ELF files.

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 specifiying --file-header, --program-headers,	--sec-
	   tions, --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.

       -s
       --symbols
       --syms
	   Displays the	entries	in 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 segment, if it exists.

       -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 are	currently sup-
	   ported.

       -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.

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

       -x <number>
       --hex-dump=<number>
	   Displays  the  contents  of	the indicated section as a hexadecimal
	   dump.

       -w[liaprmfFso]
       --debug-dump[=line,=info,=abbrev,=pub-
       names,=ranges,=macro,=frames,=str,=loc]
	   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.

       --histogram
	   Display a histogram of bucket list lengths when displaying the con-
	   tents 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.
