elfdump - dump selected parts of an object file


     elfdump [-CcdeGghikmnprsvy] [-N name] [-w file] filename...


     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, which offers an older and less user-friendly inter-
     face than elfdump, although dump may 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 pro-
     cessed using the options supplied.

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


     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.

     -i    Dumps the contents of the .interp section.

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

     -m    Dumps the contents of the .SUNW_move section.

     -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  relocation  sections  (that
           is, .rel[a]).

     -s    Dumps the contents of the symbol table sections  (that
           is,  .dynsym  and/or  .symtab)  and,  in  the  case of
           archives, dumps the archive symbol  table.  Individual
           sections  can  be  specified with the -N option, or an
           archive symbol table can be specified using  the  spe-
           cial section name -N ARSYM.

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

     -v    Dumps the contents of the version sections  (that  is,

     -w file
           Writes the contents of a section specified with the -N
           option  to the named file. This is useful for extract-
           ing an individual section's data for  additional  pro-
           cessing.  For example, extracting the .text section of
           a file can be carried out with:

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

     -y    Dumps the contents of the .SUNW_syminfo section.


     The following operand is supported:

           The name of the specified object file.
