timer

[Laura Eaves]

why not just say

sleep "$1"

instead of using a for loop? Much more efficient.
Take care.

Why not write a little script that does what you want.

Basically all you are wanting is available in linux already. A little
scripting, and you got what you want.

The simple one for a timer to run for a period of time is simply
something like

#!/bin/bash
for T <= %1 ; do
Sleep 1;
Echo $T
Done
Play alarm

NOTE: I have used pseudo code in my example, but you get the idea I
hope. The %1 is a value that you pass to the script when you call it.
For example, if you want to time something for 60 seconds you put in 60
when you call the script. The sleep 1 command tells linux to sleep for 1
second before executing the next command. The play alarm at the end of
my example is a generic statement that I used to show you that when the
loop is done you can tell the script what to do next.
