Wrap-up; Glossary terms from week 3

Congratulations! You completed another section in this course.
Take a minute to think about what you've achieved.
You learned a lot in this section. Let's recap what we covered.

In this section, you utilized the command line to communicate with the OS.
Part of this was using commands for navigating and managing the file system.
And you used other commands for authenticating and authorizing users.
These are all tasks that a security analyst is likely to encounter.

Finally, you learned about accessing resources that support
learning new Linux commands.
With this knowledge, you'll be able to continue learning more and
more about using the command line.

We did it! we learned how to communicate with Linux.
That's a great accomplishment, and
one that will be very useful to you in your career as a security analyst.
You should be proud of the work that you've done so far.
