Well, it seems that bash doesn't have some of the stuff ISTR from the
original *IX stuff (builtin alarm? not sure anymore). Anyway, a google
for "bash alarm trap" led to this and there are lots more. This was just
the first and may not be the best for your needs.


Anyway, sans "alarm", a trap, sleep, SIGUSR* or SIGINT combination should
do nicely.
