Using the Fish Shell

Fish (Friendly Interactive SHell) is a popular Linux shell which provides more and better command completions than the default BASH shell. This can save you a lot of typing.

It’s easy to give Fish a try if you like. First install it by typing this at the Linux command line:

$ sudo apt install fish

Then start the shell by typing fish:

$ fish

Use exit to quit the shell:

$ exit

You can also use other programs like Oh My Fish to easily install good-looking shell themes.

Please note that using Fish is entirely optional. The default BASH shell will work fine for this course.
