RE: how do i make a script run for a certain period of time?
Message ID:
If you want your loop to first finish
what he is doing before die, do this instead.
Thus,when you receive the alarm sig you exit
first the loop then the script.

#!/usr/bin/perl -w

use strict
my $time_to_die=0;
my $sleep=5; #in seconds
my $timeout=3600; #in seconds

$SIG{ALRM} = sub { $time_to_die=1; };
