How to compare binary files to check if they are the same?

Use cmp command. This will either exit cleanly if they are binary equal, or it will print out where the first difference occurs and exit.

I found Visual Binary Diff was what I was looking for, available on:

• Ubuntu:

  sudo apt install vbindiff
  

• Arch Linux:

  sudo pacman -S vbindiff
  

• Mac OS X via MacPorts:

  port install vbindiff
  

• Mac OS X via Homebrew:

  brew install vbindiff
  

The standard unix diff will show if the files are the same or not:

[me@host ~]$ diff 1.bin 2.bin
Binary files 1.bin and 2.bin differ

If there is no output from the command, it means that the files have no differences.
