Run a script when a file is updated

[soma01]

I am a newbie and need some help on writing a script.

I would like to do some processing just after a file has been updated (by another application); some kind of trigger on event. I would like to do this without looping.

Is this possible ?

If not, then as the file will be updated once per minute at 00 seconds, I could wait in my script until @Sec = 5, do what I have to do, then sleep (55000) and loop; but I am a bit afraid of the load the loop will put on my CPU.

Could someone just put me in the right direction ?

Thanks

If your script is sleeping, it will use 0% CPU.

Maybe this.

Local $TimeOut = 5 * 1000 ; 5 Sec
Local $TD = TimerInit()

While 1
    If TimerDiff($TD) > $TimeOut Then
        ...
        $TD = TimerInit()
    EndIf
    ...
    Sleep(10)
WEnd

I don't see how you can do it without a loop. A sleep for a few seconds wouldn't really cause a load problem (heck even if it was 100 milliseconds). You could use something like FileGetTime to see if the file has changed.
