# File permission

This linter verifies if a file has unnecessary permissions.

If a file has execution permissions (+x), file-perm will

generate a warning.

It will ignore files starting with `#!` for types of files

that typically have shebang lines (such as python, node or

shell scripts).

This linter does not have any affect on Windows.

## Run Locally

This mozlint linter can be run using mach:

```{eval-rst}

.. parsed-literal::
