Remove all untracked changes from the current directory - good for package-based installs that have a lot of untracked changes (that you don't need for what you're working on) for some reason or another.

git_rm_untracked.sh

$ git clean -fdn

# -f force (because Obi-Wan says so)
# -d also removes directories
# -n dry run (ALWAYS do this first)

# You can also specify a path, but to be safe I always just cd to where I want to destroy changes
