Elf Shell v0.43b-portable is an automated reverse engineering tool with read/write capability for the ELF format. Sophisticated output with cross references using .got, .ctors, .dtors, .symtab, .dynsym, .dynamic, .rel.* and many other with an integrated hexdump. Designed for Linux. All calls encapsulated in libelfsh.a, so the elfsh API is really reusable. Sample output here.
