Command Line Basics Part 2: Intermediate Command Line

Luke Parham

Part two of our new course, Command Line Basics, is ready today! In the second and final part of this course, you’ll move on to a few intermediate topics like customizing your shell, looking at the difference between two versions of a file, and changing file permissions.

Finally, bring your command line skills up to the next level with Bash Scripting, and find out how it can help you automate tedious tasks.

Part 2: Intermediate Command Line

  1. Introduction: In this introduction, get a quick overview of what’s to come in the second half of our course.

  2. Customizing Bash: Get a feel for what it’s like to edit config files in Bash and how you can bend the system to your will.

  3. Diff: Sometimes you need to look at what has changed between two versions of a file. If that’s the case, diff has got you covered!

  4. Challenge: Undoing a Bad Patch: And sometimes you realize you really don’t want the changes that have been made to a given file. Not to worry, the patch command has you covered there too!

  5. File System: After working with the filesystem for so long, it’s good to take a step back and think about what’s really going on. In this video you’ll get an idea of what a file really is.

  6. File Permissions: Now that you’ve seen how files work, it’s time to think about what file permissions are and how you can change them to suit your needs.

  7. Bash Scripting: Tests and Ifs: In this introduction to Bash scripts, you’ll learn how to define variables as well as how to use "tests" and if-statements.

  8. Bash Scripting: Loops and Switches: Next, you’ll learn how to add looping constructs and switch-statements to your bag of tricks.

  9. Bash Scripting: Functions: Finally, we’ll end our tour of Bash by looking at how functions work.

  10. Automating Your Job: Now that you’ve learned the basics, it’s time to test your skills by putting together a script that will make the lives of the designers on your team a little easier.

  11. Challenge: Automating Your Job – Refactoring: In this challenge, you’ll refactor your script a little bit by pulling some functionality out into a re-usable function.

  12. Conclusion: In the conclusion, we’ll recap what we’ve learned in this course, and find out where to go to learn more.
