What You Learned

You now have a better understanding of how to use the command history, how to reuse arguments from previous commands, how to run one command conditionally after another, and how to use your editor to edit the current or previous command.

You also know how to monitor your CPU and memory usage, shut down programs that may have become unresponsive, and how to suspend a program and resume it later or run programs in the background.

Next, you’ll look at tools for communicating over the Internet.
