in reply to Sleeping with the Enemy

I'm curious. How do you use select to cause the script to sleep for a time with a greater granularity then seconds?

Thanks!

    The fourth argument to select specifies a timeout. If you call it with blanks for the first three arguments and a value for the fourth it will timeout for that long. For example, you can effect a sleep of 250 milliseconds this way: 
     select(undef, undef, undef, 0.25);

    See the perlfunc bit on select...

    While sleep() is usually good enough, select() comes in handy sometimes.
