User Commands elfdump(1)
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.

User Commands elfdump(1)
-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.

User Commands elfdump(1)
-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.
OPERANDS
The following operand is supported:
filename The name of the specified object file.
