process in Gui for linux user Management/***

 

GUI (Graphic User Interface)

In Graphical Mode (GUI), we can have many shells open, it is a good thing when we are performing some tasks on multiple/remote computers. We can even log in with our username/id and password/keys through the GUI.


After successfully logging in, we are taken to the OS desktop where we can use the installed applications.


Non-graphical mode actually starts off with a text-based login, As shown below. We are generally prompted for our username/ID and after entering that, we are then prompted for our password. If the login is successful, then we are taken straight to an execution shell.



In command line interface or the CLI, there are none of the windows present to move around. Even though we have specific text editors, dedicated web browsers, and email clients, they are basically just texts. This is how UNIX got its start before the graphical environments became the norm. Most servers will be running in command line mode (CLI) too because a GUI is a waste of resources and dataspace.
