[ale] "at" question

[Andy Grover]

I'm trying to whip something up in linux to act as an alarm clock, that
is, I specify a time, or an amount of time, and my computer starts beeping
when that time arrives.

What I've tried so far is writing a little program in C that beeps a lot,
and then using at to tell the pc when to execute it, but it's not working.
The at job is just disappearing off the at queue at the appointed time.

Is there an existing program to do this, or any ways to do it other than
writing a full-blown c or perl program?

Thanks, Andy
