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.
