This is a bit of a goofy hack, but some of the options can be useful if you need a little more information on your terminal prompt. Basically, I’m using it to put a Space Invader as my command prompt.
In Terminal, open the .bash_profile file using the nano text editor
sudo nano .bash_profile
Add a new line containing the following code:
Inside the quotes, you could add nearly anything you want. There are a handful of official switches that generate specific outputs:
\WCurrent Working Directory (/Folder)
\wCurrent Working Directory, Full Path (~/Desktop/Folder)
Now, if you want to drop a Space Invader inside the quotes, just add it (or any other emoji) from the Edit>Emoji & Symbols menu.
