running command more than twice in one second?
how do i do that?

say i wanna run a check script but i want it to run at least twice in one second, what kinda script would that need? matter,

this on a sunsolaris system.

i would like it to run as many times as possible under one second but i guess i can live with 2 so does anyone know how to do this?

To repeatedly run a command as fast as possible try:
Code:
#! /usr/bin/ksh
while : ; do
      command
done

Assuming that "command" takes less than .5 seconds you should be ok.

More control can be obtained by using Perl's select statement:

#!/bin/perl

# loop
while () {
system("command");
select(undef, undef, undef, 0.25); ## Pause for 25 miliseconds
}
