git_ignore_all

This script will create a .gitignore file ignoring everything for a given Git directory ($PWD if not given).

The following parameter is optional:

f

overwrite an existing .gitignore file

The generated file contains three sections:

  1. general ignores

  2. patterns for all file extensions within the given Git directory and its subdirectories

  3. all top-level directories and files

It should be used as a starting point, i.e., you should remove entries which should not be ignored.

gitignore.io can be used to add fine-grained ignores.
