The following is an example of a typical usage of the
elfdump command:
elfdump -a -w output /bin/ls
To dump the content of '.dynsym' symbol table:
elfdump -s -N .dynsym /bin/ls
To dump the archive symbol table, but not the symbol tables of archive members:
elfdump -s -N ARSYM
/usr/lib/libelf.a
To dump the content of .got section and the symbol-versioning sections in
Solaris
elfdump format:
elfdump -S -Gv /bin/ls

The
elfdump utility first appeared in
FreeBSD 5.0.
The
elfdump utility was written by
Jake Burkholder
<
jake@FreeBSD.org>.
Later it was rewritten based on the libelf library. This manual page was
written by
David O'Brien
<
obrien@FreeBSD.org>.
Kai Wang
<
kaiw@FreeBSD.org>
rewrote it using the
ELF Access Library (libelf,
-lelf) and implemented additional functionality.
Does not fully implement the ELF gABI.
