I was tired of being asked who was the last person to use a specific machine, or vice versa. This generally isn't a big deal, but sometimes if we lost communication with the machine, I wanted to have a history of everyone who has ever logged into that machine. Every day, a few files are automatically dropped in a specific folder, and this script will run on that folder and appropriately log the changees.
run2.sh is the most up do date script--the old versions will work, but they are not as clean nor easy to look at haha
