# Purpose: Easily adding, updating and removing files from a git repo
# NOTE: The -d flag assumes your git repos are subdirectories under your home directory (for example, mine are ~/bin and ~/.dotfiles). If this is not your desired behavior remove the ~/ from line 26. Then you may enter the absolute path of the git repo with the -d flag. If that doesn't suit your fancy, you may also just 'cd' into your git repo and forgo the -d flag entirely.  # # #
