Command Line

We are going to dive into real command line work this session.

You can seriously mess up your system if you get too ambitious with the command line. If you use a Mac, you can easily start up your terminal and wipe out important files  with the rm (remove) command. This is the same on the PC if you have already downloaded GitBash. If you want to practice some  before class, use this linux emulator: This is pretend. Nothing you create here is saved. Refresh your browser and it will disappear.

We will login to OPAL today. This is where your website files will be hosted.
