Lynda.com tutorials

UCLA employees and students have access to video tutorials through Lynda.com.

One course that will be especially helpful to Hoffman2 users is "Learning Linux Command Line". This video series will help you get up to speed with commands like cd, ls, mkdir, cp, mv, find, grep, awk, sed, vi, tar, and so on. The whole series will take you about 2 hours to complete, but you are welcome to pick and choose from the individual tutorials that interest you (each video runs from about 2 to 6 minutes).
