In this short video I demonstrate how you can figure out who is logged in on your Linux Servers. I am going over 4 commands that should be available for your Linux System. In my case I needed to install the command finger since it was not pre-installed. In order to install the command finger just type in:
sudo apt-get install finger
and hit enter. This will install it and it should be available right away. The other commands I am using in this video are: who, last and lastlog. If you like to know more about those commands just type in man <name of command> and hit enter and it should present you with the manual page for the command.
Enjoy watching this video and leave comments if you know other ways of accomplishing this task. Thanks
