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, --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.

       --dyn-syms
	   Displays the entries in dynamic 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, as well as ARM unwind tables (".ARM.exidx" /
	   ".ARM.extab") 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 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 hash tables in the
	   file's dynamic section, rather than the symbol table sections.

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

       -R <number or name>
       --relocated-dump=<number or name>
	   Displays the contents of the indicated section as a hexadecimal bytes.  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.  The contents of the
	   section will be relocated before they are displayed.

       -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 command to ar, but without using the
	   BFD library.

       -w[lLiaprmfFsoRt]
       --debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges,=pubtypes,=trace_info,=trace_abbrev,=trace_aranges,=gdb_index]
	   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 that there is no single letter option to display the content of trace sections or
	   .gdb_index.

	   Note: the =decodedline option will display the interpreted contents of a .debug_line
	   section whereas the =rawline option dumps the contents in a raw format.

	   Note: the =frames-interp option will display the interpreted contents of a
	   .debug_frame section whereas the =frames option dumps the contents in a raw format.

       -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.
