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, --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.

       -S
       --sections
       --section-headers
           Displays  the  information contained in the file’s section headers,
           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  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[liaprmfFsoR]
       --debug-dump[=line,=info,=abbrev,=pub-
       names,=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 con-
           tents 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.
