in reply to Complicated regexp problem

(a-z_) should probably be ([a-z_]*), or better yet, (\w*).

You're asking for trouble by putting your pattern in a string before using it in a regex. To avoid multiple-quoting headaches, use qr like this:

my $regexp = qr{(?:ftp:\/\/)?\/{5}(a-z_)\/}; if ($link =~ /$regexp/) { ... }

    No need to escape the slashes as you are not using them as delimiters.

    my $regexp = qr{(?:ftp://)?/{5}(a-z_)/};
