  Command Line Interfaceand Bourne-Again Shell A CLI is a command line interface where the users type in text commands to interact with the program underlying the interface. The most important aspect of any CLI is it can be easily automated using scripting in some programming languages that it supports. Bash or Bourne-again Shell, is the newer version of the Bourne UNIX shell, and is found in most of Linux based operating systems. It is the default login shell. You can find it even on certain versions of Windows ( WSL, ;) ). Your basic Windows Command Prompt is a perfect CLI, but once you get the taste of bash, there’s no going back, especially if you are interested in DevOps, Scripting and Automation.

  Can’t remember? Don’tremember. GitHub Desktop is a GUI interface for Git programs, and can easily do all the work you can do with a git shell, but without the need of remembering the commands. Just install, login. You’ll be able to see all the commands in there. It is essentially the Windows XP to the MS DOS, in the way that, you can do the same stuff in both, but you don’t need to remember 100 lines of code to just switch from one folder to another and just click and finish the job.
