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  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.

       -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 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  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[liaprmfFsoR]
       --debug-dump[=line,=info,=abbrev,=pubnames,=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.
