Bash - countdown timer
Hello, I have another problem with my script - I would like to have a countdown timer visible on the screen, and at the same time, I want te be able to do something else. And when the time runs out, I need to know about that inside the script somehow and do some action. I guess that would require 2 threads to achieve that but maybe there is another solution in bash?
Maybe there is some equivalent to fork() - and to give both processes different task to do?
Thanks in advance.

stopwatch
STOPWATCH(1x) STOPWATCH(1x)
NAME
stopwatch -- a stopwatch and timer program
SYNOPSIS
stopwatch
DESCRIPTION
stopwatch does what its name implies - enables hand timing much like a physical stopwatch. It can also be used as a countdown timer. Stop-
watch has millisecond accuracy and no artificial limit on hours.
DIRECTIONS
Press "start" to start the stopwatch and "stop" to stop it. "record" records the current time and selects it so that it can readily be
pasted into other programs. Recorded times are marked with an L for "lap" or T for "total". When stopped, you can cut/paste/edit the time
by hand and set it to any valid time. "zero" resets the time to zero. Holding down the shift key while pressing record or zero, records and
then zeros the time.
Time moves forward or backward according to the Run menu. By default, time is stopped automatically when either the lap or total time
reaches zero. To disable the automatic stop, unselect Run -> Stop At Zero.
