It's worth mentioning that you can create several nested directories with -p this way:

// ~/
$ cd -
Also, just "cd" is same as "cd ~" which brings you to the home dir.✔️

I'm planning on covering aliases in another blog post for this series! They are actually something relatively new to me, so thank you for introducing this one to me and adding to the discussion.
Thank you for the article, Victoria. You and those who read this article might benefit from explainshell, a website where you can enter a shell command (with optional arguments) and it will explain to you what everything means.
Try it out by entering some command with arguments. :)
That link is absolutely amazing! I wish I would have known about it earlier. I'm going to edit the article and add it. Thank you so much for adding this to the discussion.
