+To participate in this Library Carpentry lesson, you will need a working Unix-like shell environment.
 Specifically we will be using Bash ([Bourne Again Shell](https://en.wikipedia.org/wiki/Bash_(Unix_shell))) which is standard on Linux and macOS. macOS Catalina users will have zsh (Z shell) as their default version.
 Even if you are a Windows user, learning Bash will open up a powerful set of tools on your personal machine, in addition to familiarizing you with the standard remote interface used on almost all servers and super computers.

 >- **Linux:** The default shell is usually Bash, but if your machine is set up differently you can run it by opening a terminal >and typing `bash`.  There is no need to install anything. Look for Terminal in your applications to start the Bash shell.
