alarm --
send SIGALARM in specified number of seconds
Synopsis
alarm seconds
Description
Instructs the system to send a SIGALRM signal in
the specified number of seconds. This is a floating point
number, so fractions of a section may be specified. If
seconds is 0.0, any previous alarm request is
canceled. Only one alarm at a time may be active; the
command returns the number of seconds left in the previous
alarm. On systems without the setitimer system
call, seconds is rounded up to an even number of
seconds.
