	     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.	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 equiv-
     alent.  At least one option besides -v or -H must be given.

     -a
     --all
	 Equivalent to specifiying --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.

     -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 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  ex-
	 ist.

     -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  sec-
	 tion.

     -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.

     -w[liaprmfFsoR]
     --debug-dump[=line,=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.

     -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.
