Odd question but if someone hacks into your system, what would 'who' display?
For most Desktop Linux users, there really isn't a reason to run this command. I would also think that the information displayed by 'who' is fairly consistent, so... wouldn't running 'who' in the background to compare the normal state vs an abnormal state indicate the presence of an unknown user (a possible hack into the a system that only has ONE real user)?
