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 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.

       -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
	   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,=frames-interp,=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.

       -I
       --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.
