Thanks @HaKuNa.
I used this command to get the log:
tail -f /var/log/openhab2/openhab.log
This is what I got so far:
[18:27:24] openhabian@openhab : ~ $ tail -f /var/log/openhab2/openhab.log -f /var/log/openhab2/events.log
==> /var/log/openhab2/openhab.log <==

Tried to use the < code > to format the code. Hope I did it right.
