Game organizer bash script.

organize_games

#!/bin/sh
#
# Organizes a directory of games into a more convenient layout:
#
# Games/
# - 0-9/
# - A/
# - B-D/
# - E-H/
# - I/
# etc. etc.
#
# Copy this script into /usr/local/bin.
#
# Usage: organize_games max
#
# $max is the maximum amount of games per directory.
# This is merely a suggestion. If there are 100 games that start with S, setting
# $max to 25 still creates a directory of 100 games.
