• Why use a terminal or command line?
– The terminal is a powerful and invaluable tool that can be used to perform many useful tasks you might not be able to accomplish with a GUI
– The command-line interface is sometimes a faster way to accomplish a task.
– Learning the command-line interface is the first step towards more advanced troubleshooting, system administration, and software development skills
– Gives access to a ‘shell’
