       readelf - Displays information about ELF files.

       readelf [-a|--all]
	       [-x <number or name>|--hex-dump=<number or name>]

       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.

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

	   Equivalent  to  specifying --file-header, --program-headers, --sec-
	   tions, --symbols, --relocs, --dynamic, --notes and  --version-info.

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

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

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

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

	   Displays the detailed section information. Implies -S.

	   Displays the entries in symbol table section of the file, if it has

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

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

	   Displays  the  contents of the file's relocation section, if it has

	   Displays the contents of the file's unwind section, if it has  one.
	   Only	 the  unwind  sections	for  IA64 ELF files are currently sup-

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

	   Displays  the contents of the version sections in the file, it they

	   Displays architecture-specific information in the file, if there is

	   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.

	   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

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

	   Display the version number of readelf.

	   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.

	   Display the command line options understood by readelf.

	   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

	   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.
