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  examining  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,  --sec-
           tions,  --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.

           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  sup-
           ported.

       -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  sup-
           ported.

       -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[liaprmfFso]
       --debug-dump[=line,=info,=abbrev,=pub-
       names,=ranges,=macro,=frames,=frames-interp,=str,=loc]
           Displays the contents of the debug sections in the file, if any are

       -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.
