python script for git on public machines, to force users to provide their author name to commits

git_author_checker.py

#!/bin/usr/python3
# This script analyzes the given arguments and if no "--author" is included in the argument list it forces the user to
# enter his credentials. To force all git calls to pass this script, set this as an alias in the .bashrc or the
# .bash_aliases by adding the following line:
# alias git='python3 <path_to_this_script>'
