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, --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.

       -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.

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

       -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 infomation contained in  the	header
	   part	 of binary archives.  Performs the same function as the t com‐
	   mand to ar, but without using the BFD library.

       -w[lLiaprmfFsoR]
       --debug-dump[=rawline,=decodedline,=info,=abbrev,=pub‐
       names,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges]
	   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: the =decodedline option will display the interpreted contents
	   of a .debug_line section whereas the =rawline option dumps the con‐
	   tents in a raw format.

       -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.

       @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  charac‐
	   ter	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.
