1 - About

objdump is a disassembler that displays information about object files.

It is mostly used for inspecting assembly code

3 - Syntax

objdump -d fileName
# Tip
objdump -d fileName| less
# Intel Syntax with M (Default syntax is AT&T)
objdump -M intel -D fileName| less
# 32-bit mode: i386 display assembly content using 32-bit layout
objdump -M i386,intel -D fileName | less

where the following options:

  • d (Default) only displays assembled contents of executable sections.
  • D displays assembly contents of all sections. -d is implicitly assumed.
  • S include source code
  • M defines the syntax output

The output is generally an OS / Linux - Executable and Linkable Format (ELF)
