How do I get a bash script working on FreeBSD, OpenBSD and Linux without modifying it?

Sorry, the headline might be a bit irritating, but I didn't know anything better. Anyway, I want a bash script to work on FreeBSD, OpenBSD and Linux without modifying it, but bash isn't located at the same place in Linux and BSD.

So, if I write #!/bin/bash then it won't work on BSD, because the bash shell is located in /usr/local/bin/bash there. Is there any solution to get this script working on both?

Or do I really need to ship two scripts with different paths...?

Solution

  • Using env in the shebang (#!/usr/bin/env bash) should make the script OS agnostic.
