How to disassemble a binary executable in Linux to get the assembly code?

Question

I was told to use a disassembler. Does gcc have anything built in? What is the easiest way to do this?

Answer 1

there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

[later] you might also want to check out Albert van der Horst's ciasdis: http://home.hccnet.nl/a.w.m.van.der.horst/forthassembler.html. it can be hard to understand, but has some interesting features you won't likely find anywhere else.
