UNIX

Most of our systems (and general HPC resources) run some UNIX derivative. Much of the software is command line based, so it's worthwhile to learn the basics.

There are tons of free resources on the web for getting started, for example this book. There should also be a "for dummies" book in the lab.

As you find resources that are helpful, please update this page.
