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.  At the moment, readelf
       does not support examining archives, nor does it support examing 64 bit
       ELF files.

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 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.
