Exercises

Answer the following questions (or at least as many as you can figure out) in this document. For all the questions, use the 100k words. Give your answer for each exercise, and show the command you used to get it. Each question can be answered using a single Terminal command, though you might need to use a number of pipes.

If you want to be really stylish, put your code inside of backticks like this:
