Experiment with a CLI

The CLI on Your Computer

1. Start a Shell window on your computer:
   • On Microsoft Windows, start a Command Shell or a PowerShell by running cmd.exe or powershell.exe
   • On Mac OS X, start a Terminal Shell by running the Terminal application
   • On Linux, start a BASH Shell by running any terminal window such as Gnome-Terminal
2. In the Shell window, enter these two commands:

   echo %cd%     (windows: displays current directory path)
   dir           (windows: lists files in the current directory)
   
   pwd           (Mac OS X and Linux: displays current directory path)
   ls -l         (Mac OS X and Linux: lists files in the current directory)
