Re: Removing lines from a file.

Your logic is flawed. Instead of this:

  if ($_ !~ /^zone \"$domain\" \{/ .. /\}\;/)
[download]

you should really have this:

  unless (/^zone \"$domain\" \{/ .. /\}\;/)
[download]

Why? In your version you use the (/A/ .. /B/) syntax to extract a range of lines between /A/ being true and /B/ being true. When you test for ($_ !~ /A/ .. /B/) then you get everything between /A/ being false and /B/ being true. That's not what you want.

Yes! You nailed it! That makes perfect sense now. I will use unless more often now instead of making my life difficult. You reply really helped me out!	[reply]
