Match (and delete) LF character in Notepad++ regex

Question

Answer 1

Using common sense I would suggest following approach:

1. Replace all the CRLFs with some special string (that you are sure is not present in file), say "fuuuuuu!!!".
2. Replace LFs with empty string.
3. Replace all the special strings ("fuuuuuu!!!") back with CRLF.

And you are done.
