Problem
I. Quigley told you that one of the most useful tools of a system administrator is the cat command. They assured you that this isn't a hazing thing and that you should write some simple plain English documentation for cat since the man page is a little dry. Make sure to include examples!
II. Quigley told you that one of the most useful tools of a system administrator is the echo command. You're almost certain that this is a hazing thing, but they're paying you well enough that you'll do it. Write simple plain english documentation for the echo command. Don't forget the examples!
III. While cat and echo are on your mind, Quigley said that you should strike while the iron is hot and write some documentation about how to make use of pipelines on the command line. Those two commands should help you come up with some nice examples.
IV. Speaking of the echo command, Quigley told you that it is the perfect tool to illustrate expansion on the command line. That reminded them that you should probably explain how expansion works. Explain how you can use basic filename expansion to make your job as a system administrator a little bit easier.
V. While working on all the previous tasks, you realized just how much typing is involved in being a system administrator. When you mentioned this to Quigley they thought for a moment and then told you that there's a ton of handy techniques to save you keystrokes that you should include in your documentation. Looks like you're never going to mention anything to your supervisor again.
Make a simple cheatsheet of common Linux keyboard shortcuts that you can see yourself using, maybe even include some examples. Also include information about how to effectively use the command history.
