Conceptual Aside: The command line interface

Big Word

Command line interface: A utility to type commands to your computer rather than clicking

• Bash on linux
• Terminal on Max
• Command Prompt on Windows (Powershell)

Arguments: Values you give your program that affect how it runs

Essentially passing parameters to a function

Commonly used commands:

• ls on linux
• dir on windows
• cd : change directl
• dir /w
• dir /w /p
• cd ..
• mkdir test

Another Alternatives

Windows Powershell --> can use ls now
