When using Linux Mint / Ubuntu or any *nix based system, it is quicker and actually efficient to get tasks done directly using the Terminal instead of the point and click stuff.
Here is a simple command that will show you who has logged into the current system plus when the system was last booted up in Linux Mint and Ubuntu :
1. Open Terminal and type who -u -b
2. That’s it! This brings up a list of users logged in along with the time when the system was started, all in one go.
By the way don’t be surprised by simple commands like the above, these commands in Linux make the system so robust and versatile.
For more information on how to use commands effectively in Linux, we have a free e-book that can help.
