Installation

You might already have a shell installed.

• If your computer is running Linux, you almost certainly have a shell called Bash installed on your computer already. See the Linux section for instructions on how to access it.

• If you're running MacOS, you've already got a shell called zsh. See here to learn how to access it.

• If your computer runs Windows, you'll want to install the Windows Subsystem for Linux (WSL). See here.

Once you've got a shell installed, you'll be able to open your terminal and do something like this:

$ echo "Hello, world!"
Hello, world!
