ELFFILE...

   `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.  At the moment,
`readelf' does not support examining archives, nor does it support
examing 64 bit ELF files.
   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',
     `--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.
`-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
     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.
`-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,=pubnames,=ranges,=macro,=frames,=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.
`--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'.
