I am on my Linux bible 9th edition,
I typed the command
who -uH
The output is here.
NAME LINE TIME IDLE PID COMMENT
systemadmin tty2 2016-09-03 22:50 01:33 1902 (:0)
Notice the (:0)
So only I am logged into TTY2, however, the bible told me that
PID shows the process ID of the users login shell.
COMMENT would show the name of the remote computer the user has logged in from.
The example in the bible shows that chris is on tty1 with a PID of 2013. As you can see my output is different, so I suspect a hacker has pwn3d my system. Can any good Linux Voaters give good advice on this??
EDIT: Fix formatting.
