If you're an experienced command line user, this is a great reminder of how far you've come, and check list to figure out where your weak spots lie. I wonder how long these skills will remain useful; skeptics often seem to (wrongly) think that the CLI is 'obsolete.' I learned some of the things on this list more than 10 years ago and I am sure for some people it has been much longer than that. If anything, the increased prevalence of embedded Linux devices has made these skills feel more useful over time.
