Utility script: prints out non-file-associated meta files in a given unity directory, with the git command to remove them

clean_meta_files.py

import os
import sys

if __name__ == '__main__':
    if len(sys.argv) > 1:
        os.chdir(sys.argv[1])

    target_dir = './Assets'

    dir_meta_files = set([
        os.path.join(path, file)
        for path, dirs, files in os.walk(target_dir)
        for file in files
        if file.endswith('.meta') and len(file.split('.')) == 2
    ])
    print("git rm %s" % ' '.join([
        '"%s"' % file for file in dir_meta_files
    ]))

useful if you forgot to add this: https://answers.unity.com/questions/547795/ignoring-folder-meta-files-on-version-control.html, and have a bunch of directory-associated meta files that you want to remove
