I wrote this course, an introduction to using the command line: https://www.coursera.org/learn/unix

Oh! Speaking of command line and the basics, this one from MIT is amazing. Covers all the basics.

I'm the lead developer of swirl. Let me know if you have any questions or comments.

Thanks for your work on this. Been immensely helpful for this newb.

One piece of advice, I would ensure QA tests include checks to make sure that the skip function works. When the ggplot package was updated, the update broke the Getting and Cleaning data module, the ggplot units. The questions were not answerable and the skip function didn't work either.

You are the reason I was able to pass the R programming unit, John Hopkins Coursera. Thank you sooooo much.

Several professors at my school highly recommend Swirl to students brand new to programming, and the results have been pretty good overall. Thanks for working on this!
