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.

  User Management in Linux   A user is an entity, in a Linux operating system, that can manipulate files and perform several other operations. Each user is assigned an ID that is unique for each user in the operating system. In this post, we will learn about users and commands which are used to get information about the users. After installation of the operating system, the  ID 0 is assigned to the root user  and the IDs 1 to 999 (both inclusive) are assigned to the system users and hence the ids for local user begins from 1000 onward . In a single directory, we can create 60,000 users.    User Management Command User management is nothing but adding, deleting the users and assigning the passwords for the users in Linux . The same follows with groups. The important thing is this command needs root privilege for accessing other users or groups. Only the same user process can be done without the privilege.

Programmers who have access to a computer program's source code can improve that program by adding features to it or fixing parts that don&#
