Summary

As you can see, the command line is very powerful for everyday tasks. We learned how to do basic things, such as create files and directories, and navigate a system via the command line. We learned about manual pages, where to find help, and how to customize the shell.

In the next chapter, we'll take what you learned here and apply it against a real dataset. Feel free to come back to this chapter as it will be helpful throughout the rest of this book.
