In the text that follows all the basic tasks will be explained through their commands and its use and application.

Each user can only log-in to the Linux terminal through a specific username either assigned or created. This is because different users are connected to the same server through different terminals thus without an assigned user name logging in wont be possible. During the Installation, a root user' or super user' account is created which has unlimited access to all the system files and resources. Usually it is best to only access it to perform certain administrative tasks such as program installation.

Once logged in through root user for the first time another user can be created through adduser(space)name' command.

The user can also be placed in a group by creating a new group through addgroup(space)name' command.

Logout is a bit simpler when you're done with your work you can select logout at the main menu and click ok in the dialog box to confirm. Once logged in through a user id, multiple tasks can be done starting from the simplest looking at the directory of files and folders through the dir command.

Server operators when serving multiple operators can change access permissions through the chmod' command. Disk management commands include df' command to display free disk space, du' for estimated file space usage, qouta' command to display disk usage or limits, reboot' is used to reboot the system and ddrescue' for data recovery tool . Server operators would also require sometimes abort a certain operations taking place through kill' command which stops a certain process from running and killall' which kills processes by names. At any given time the list of all the users currently logged in can be seen by using users' command. ulimit' command can be used to limit user resources.
