elfdump


NAME
     elfdump - dumps selected parts of an object file

SYNOPSIS
     elfdump    [-cCdegGhHiklmnprsuvy]    [-N name]     [-w file]
     filename...

DESCRIPTION
     The elfdump utility symbolically dumps selected parts of the
     specified  object  file(s).  The options allow specific por-
     tions of the file to be displayed.

     The elfdump utility is similar in function  to  the  dump(1)
     utility.  The  dump  utility  offers an older and less user-
     friendly interface than elfdump, although dump might be more
     appropriate for certain uses such as in shell scripts.

     Archive files, produced by ar(1), can also be inspected with
     elfdump.  In  this  case,  each object within the archive is
     processed using the options supplied.

     For a complete description  of  the  displayed  information,
     refer to the Linker and Libraries Guide.

OPTIONS
     The following options are supported:

     -c              Dumps section header information.



     -C              Demangles C++ symbol names.



     -d              Dumps the contents of the .dynamic section.



     -e              Dumps the ELF header.



     -g              Dumps the contents of the .group section.



     -G              Dumps the contents of the .got section.




     -h              Dumps the contents of the .hash section.



     -H              Dumps the contents of the .SUNW_cap hardware
                     and software capabilities section.



     -i              Dumps the contents of the .interp section.



     -k              Calculates    the    ELF    checksum.    See
                     gelf_checksum(3ELF).



     -l              Displays long section names without  trunca-
                     tion.



     -m              Dumps the contents of  the  .SUNW_move  sec-
                     tion.



     -n              Dumps the contents of the .note section.



     -N name         Qualifies an option with  a  specific  name.
                     For  example,  in  a file that contains more
                     than one symbol table, the .dynsym table can
                     be displayed using:


                     example% elfdump -s -N .dynsym filename



     -p              Dumps the program headers.



     -r              Dumps the contents of the .rel[a] relocation
                     sections.




     -s              Dumps the contents of the .dynsym and  .sym-
                     tab symbol table sections. For archives, the
                     archive symbol table is also dumped. Indivi-
                     dual  sections  can be specified with the -N
                     option.  An  archive  symbol  table  can  be
                     specified  using the special section name -N
                     ARSYM.

                     In the case of core files, the  shndx  field
                     will  have  the  value  "unknown"  since the
                     field does not contain the valid values.

                     In addition to  the  standard  symbol  table
                     information, the version definition index of
                     the symbol is also provided  under  the  ver
                     heading.



     -u              Dumps the contents of a frame unwind.



     -v              Dumps the contents of the .SUNW_version ver-
                     sion sections.



     -w file         Writes the contents of  a  section  that  is
                     specified  with  the -N option, to the named
                     file. For example, extracting the .text sec-
                     tion of a file can be carried out with:


                     example% elfdump -w text.out -N .text filename



     -y              Dumps the contents of the .SUNW_syminfo sec-
                     tion.
