Can’t believe I hadn’t come across this one before anywhere. You know the scenario when you’re debugging some wack crash or non-functionality in your Linux box and doing this over and over again:

less /var/log/messages

for reviewing what happened, then CTRL+C and:

tail -f /var/log/messages

to monitor what happens when you changed something.

Well how about just staying in less and pressing F. Discovered from less’ very own help page.

F Forward forever; like "tail -f"
