shebang-not-executable (EXE001)#

Derived from the flake8-executable linter.

What it does#

Checks for a shebang directive in a file that is not executable.

Why is this bad?#

In Python, a shebang (also known as a hashbang) is the first line of a script, which specifies the interpreter that should be used to run the script.

The presence of a shebang suggests that a file is intended to be executable. If a file contains a shebang but is not executable, then the shebang is misleading, or the file is missing the executable bit.

If the file is meant to be executable, add a shebang; otherwise, remove the executable bit from the file.

This rule is only available on Unix-like systems.
