How do I write a regular expression to find all lines containing 665 and not having .pdf
I can't seem to find how to do not in regex. This is for Notepad++ syntax if it matters.
Thanks

The feature you'r looking for is look ahead patterns
665(?!.*\.pdf)
If .pdf
will only occur after 665
, the negative lookahead assertion 665(?!.*\.pdf)
should work fine. Otherwise, I prefer to use two regexs, one to match, one to fail. In Perl syntax that would be:
/665/ && !/\.pdf/
