DESCRIPTION

       readelf displays information about one or more ELF  format
       object  files.  The options control what particular infor­
       mation to display.

       elffile... are the object files to be  examined.   At  the
       moment,  readelf  does not support examining archives, nor
       does it support examining 64 bit ELF files.


OPTIONS

       The long and short forms of options, shown here as  alter­
       natives,  are  equivalent.  At least one option besides -v
       or -H must be given.

       -a
       --all
           Equivalent  to   specifiying   --file-header,   --pro­
           gram-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

       -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  sec­
           tion, 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.

       -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

       -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 read­
           elf.
