I just saw that one of my dies returned "Inappropriate ioctl for device" at the end of the string I wanted to be returned. Is it something I need to worry about, or can I safely ignore it? I've tried to figure out what it means, and what I did wrong from various Google searches and reading here and elsewhere about it. I just do not understand it. So, other than knowing that "ioctl" stands for "input/output control" and I did something inappropriate with it, I am a bit lost.

So, do I dive in and drive myself a little crazy trying to figure it out? Can I safely ignore it, not letting it worry me? Could it bite me later?

Here is the code where I got the message.

  die "$_ isn't using strict, $!"   if ($loop == 1 && $line !~ /use st
+rict/ && $_ !~ /index/);
  die "$_ isn't using strict, $!"   if ($loop == 2 && $line !~ /use st
+rict/ && $_ =~ /index/);
  die "$_ isn't using warnings, $!" if ($loop == 2 && $line !~ /use wa
+rnings/ && $_ !~ /index/);
  die "$_ isn't using warnings, $!" if ($loop == 3 && $line !~ /use wa
+rnings/ && $_ =~ /index/);
