Ok, I see, so the code should look somehow like this: #! /usr/bin/perl
use
warnings;
use
strict;
$command = "ls
-l";
while (system($command) != 0)
{
my
$c++
}
But how could I test if the command executes if the return value changes?
...is there a unix command or other way that generates random/different
return values??
