Sounds good. Is there any situation in which this wouldn't work? I can't think of one

"#!/bin/bash" specifies that the path of bash is under the bin directory. Once there is no bash command in the bin directory, the execution will fail, but usually this is unlikely to happen unless the user changes the bash command, such as , with multiple versions of the bash command installed. "#!/usr/bin/env bash" will look for the bash command according to the path set in the environment variable.

Hahahaha, you're right to be worried, but I can't think of any scenario that could go wrong either. I have tested it on mac and linux and it is normal

Can you try retriggering tests? I think that's an unrelated failure
