Hi Brian,
you actually have many more options to leave a tail -f.

What other key can you press to exit tail that is not likely
to also be a control-signal. I.e. I think what may be wanted here is
pressing 'q' or something similar?
This would require a small addition of code to monitor stdin
and, perhaps itself send a SIGHUP to parent and exit. But it guarantees
that that an uncaught SIG won't end up being sent to the parent.
For example:
for f in /tmp/*;do
tail -f "$f"
done
That code prints the tail of the 1st file in the dir. But if I press
control-c, it also kills the for-loop.
Perhaps that is undesired?
....wow...what do you know...
that was EXACTLY what was wanted.
Some simple keypress to allow an exit.
What is it with all the complexity and non-intuitive methods to kill it?
