Command line (February 1)
How to practice using the Unix/Linux command line:
- Running commands on your local machine:
- For Linux and macOS: you can use the built-in Terminal. Another option is to install Git Bash.
- For Windows: although Windows comes with something called the Command Prompt, it is not as powerful as the Linux command line. To mimic the real thing, you may install Git Bash or WSL (Windows Subsystem for Linux).
- Using the Linux computers on campus:
- Computers running Linux are available in the WEB (West End Building, the red two-story building near Ocean Avenue).
- Username and password information is here.
- You can connect to these machines remotely from your own; follow the instructions here (not written by me).
- Note for Windows: you do not really have to download the program as the instructions say. You should be able to use SSH directly in the Command Prompt as in the Mac Terminal.
- In the browser: for any operating system, you can use Replit’s console (or shell), which is a Linux command line.
- Note: many IDEs, such as IntelliJ IDEA and Visual Studio Code, allow you to open a command line (they may call it a “terminal”) within the IDE.
