python script that tells you which local files are not part of a perforce depot

p4-local-status.py

#! /usr/bin/env python

# For this script to work you have to install `p4` (Helix command line client)

# This script will tell you if you have local files that are not part of the depot.
#
# Usage example:
#     tools$ p4-local-status.py
#     folder: tools
#     p4-local-status.cmd - no such file(s).
#     p4-local-status.py - no such file(s).
#     foobar.md - no such file(s).
