shebang

Most executable files should only use one of the following shebangs:

• #!/bin/sh
• #!/bin/bash -eu
• #!/bin/bash -eux
• #!/usr/bin/make
• #!/usr/bin/env python
• #!/usr/bin/env bash

This does not apply to Ansible modules, which should not be executable and must always use #!/usr/bin/python.

Some exceptions are permitted. Ask if you have questions.
