"The big deal is that Unix is the 800 lb. gorilla of the IT world. While desktops and laptops are usually a pretty even split between Windows and Mac, the server world is almost entirely Unix (either Linux or BSD, both of which are UNIX variants). If you work in a reasonably technical position, you have probably had to log in to one of these Unix servers before to do something. If you are in library school and looking to get a tech oriented library job after graduating, this WILL happen to you, maybe even before you graduate (a good 50% of my student worker jobs were the result of knowing Unix). As libraries move away from vendor software and externally hosted systems towards Open Source software, Unix use is only going to increase because pretty much all Open Source software is designed to run on Linux (which is itself Open Source software). The road to an Open Source future for libraries is paved with LIS graduates who know their way around a command line."
