What a great tutorial. This was definitely an underserved portion of the learning process. Also, learned `cd -` and I think my days will be ever so slightly but definitely better for it. Thanks for sharing!

Also definitely go into why `rm -rf` is such a dangerous command, by that stage in the tutorial the reader has likely begun feeling confident experimenting but has yet to encounter anything really dangerous.

There are times i wish rm had a dry run kind of switch, where it would list out all the files that would be affected before asking for approval.
