A quick tip to improve the legibility of your code is to avoid doing this:

if ($fi eq "\n")
{
 exit;
}
else
{
  # some other code here
}

There is no need for the else when the first branch terminates, so you can just write

if ($fi eq "\n")
{
 exit;
}
# some other code here

[download]

This applies for any terminating action just as exit, die, croak, return, etc. I find that it especially adds clarity if you have several such branches in succession.
