I don’t know the exact use case or how /whowatch/ works, but the |

Add this to |.cshrc| if |csh| or |tcsh| is your shell, and you will be
notified whenever someone logs in/out.
Yes, I have this in my .tcshrc.set (included by .cshrc)
whowatch is good in interactive mode, listing all processes owned by
user, or the tree of all processes similar to what pstree produces:
1 users: (0 local, 0 telnet, 1 ssh, 0 other) load: 0.15, 0.20, 0.22
57 processes

enter - users list, c - cmd, o - owner, ^I - send INT, ^K - send KILL
You can then navigate this tree using the arrow keys on your keyboard
and send INT or KILL to the selected process.
It's nothing magical, but it used to be very convenient (it doesn't work
for me anymore).
Kind regards
