This exercise is to help you get your computer set up for commandline use before our first meeting on February 1. If you can do this before class, everyone's life will be simpler. It shouldn't take you more than 20-30 minutes, depending on your computer and your previous experience.
If you have a Mac, things will be simple (he said optimistically).
run the Terminal app, which you can find under Applications / Utilities if you like use Preferences to set fonts and colors drag Terminal to the dock for easier access laterThe default Mac Terminal window looks something like this:
If you have a Windows 11 laptop, you will have to install a package called WSL (Windows Subsystem for Linux), which will give you access to all the standard commandline tools that already exist on Macs. The official Microsoft instructions are here, but if everything goes smoothly, this is it:
Start PowerShell Start / All apps This should open a window similar to the one below.
Type wsl --install and push Enter or Return This should start a longish process of downloading, at the end of which a new Terminal-like window opens.At this point, you should be at the same stage as macOS users.
Now, for everyone:
Type date and push Enter or Return. Don't type the dollar sign!
$ date you should see the current date and timeNow type
$ echo hello there it should reply hello thereFinally, type
$ pwd prints the name of the folder that you are currently in
If you get this far, you're in good shape, and you can start to play with the material in Studio 1.
