I've come across the following bit of code:
print PIPE "This is line number $_\n" and $count++;
This will only increment $count if print returned a "true" value.
How does this differ from:
print PIPE "This is line number $_\n";
$count++;
This will always increment $count.
What you probably want is:
print PIPE "This is line number $_\n" or die "Cannot print to pipe: $!";
$count++;
