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   specifying   --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.

       -t
       --section-details
           Displays the detailed section information. Implies -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 or name>
       --hex-dump=<number or name>
           Displays  the  contents  of  the indicated section as a hexadecimal
           dump.  A number identifies a particular section  by  index  in  the
           section  table;  any other string identifies all sections with that
           name in the object file.

       -p <number or name>
       --string-dump=<number or name>
           Displays  the  contents  of  the  indicated  section  as  printable
           strings.   A number identifies a particular section by index in the
           section table; any other string identifies all sections  with  that
           name in the object file.

       -c
       --archive-index
           Displays  the  file symbol index infomation contained in the header
           part of binary archives.  Performs  the  same  function  as  the  t
           command to ar, but without using the BFD library.

       -w[lLiaprmfFsoR]
       --debug-dump[=rawline,=decodedline,=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.

           Note: the =decodedline option will display the interpreted contents
           of  a  .debug_line  section  whereas  the =rawline option dumps the
           contents in a raw format.

       -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.

       @file
           Read command-line options from file.  The options read are inserted
           in place of the original @file option.  If file does not exist,  or
           cannot  be read, then the option will be treated literally, and not
           removed.

           Options  in  file  are  separated  by  whitespace.   A   whitespace
           character  may  be  included in an option by surrounding the entire
           option in either single or double quotes.  Any character (including
           a  backslash)  may  be  included  by  prefixing the character to be
           included with a backslash.  The file may itself contain  additional
           @file options; any such options will be processed recursively.
