objdump is a command-line program for displaying various information about object files on Unix-like operating systems. For instance, it can be used as a disassembler to view an executable in assembly form. It is part of the GNU Binutils for fine-grained control over executables and other binary data. objdump uses the BFD library to read the contents of object files. Similar utilities are Borland TDUMP, Microsoft DUMPBIN and readelf.
On certain platforms (e.g. macOS), the objdump binary may actually be a link to LLVM's objdump, with different command-line options and behavior.[citation needed] otool and nm perform analogous functions for Mach-O files.[1][2]
Example
For example,
$ objdump -D -M intel file.bin
This disassembles the file file.bin, showing its assembly code in Intel syntax.
Example output:
