How long does my program take to run ?

How long does my program take to run ?

How long does my program take to run ?

(OP)
i need to know, in fractions of a second, how long my script/program takes to run.  i've already tried the "time" and "date" commands, but i only get increments of whole seconds.

any suggestions would be most welcomed !

RE: How long does my program take to run ?

How about this script ? Let the program runs 500 times . Thus u can see the time .

#!/bin/sh
i=0
while [ $i -lt 500 ]
do
who >& /dev/null
i=`expr $i + 1`
done
exit 1

i=0
while [ $i -lt 500 ]
do
./yourProgram
i=`expr $i + 1`
done
exit
