Well I have been experimenting with sleep <secs> to give me a smaller time accurate to about + or - 5mS on this MacBook Pro, OSX 10.7.5.

It would be good enough for the Egg_Timer.sh and passes the ShellCheck test.

It is fully posix compliant with SLEEPs unity seconds timer only.

Boy am I gonna get some flak over this one, (yes I bend the rules a little)... ;o)

Code:

#!/bin/sh
# delay.sh <secs> <millisecs[0-999]>
secs="$1"
millisecs=$( awk -v mS="$2" -v correction=0.94 ' BEGIN { print (( mS / 2 ) * correction ); } ' )
millisecs="${millisecs%.*}"

# Accuracy on my MBP OSX 10.7.5 + or - 5mS of FSD.
mS()
{
	loop=0
	while [ "$loop" -le "$millisecs" ]
	do
		sleep 0
		wait
		loop=$(( loop + 1 ))
	done
}
# Test the mS function only.
time mS
sleep "$secs"

As I quoted in a previous post I could create a resonably accurate timer using 'afplay', 'aplay' or '/dev/dsp'. I might use afplay and make it Apple dedicated...

Thanks Don for the info...

I await the flak... ;o)
