How to sleep for less than 1 second in unix shell script 1

[GrahamBright]

Hi,

I'm looking for a way to sleep for less than 1 second in unix.

if [ -f $MSISDN_FILE ] ; then
while read LINE
do
echo $LINE
#call script
#sleep $1 << not sufficent 1 second is too long
done < $MSISDN_FILE

I can't find any examples of how to use usleep() for this task as this I belive would be perfect.

Example:
I would like to execute a perl script with every half a second but this isn't possible using standard sleep?

Some sleep(1) commands as the GNU one support this. Maybe better get one of those.. having perl involked all the time may surprise you with excessive CPU usage.
