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.

     -N
     --full-section-name
         Displays the full section name for -S.

     -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.
