Regex match string that starts with but does not include

I'm trying to match file paths that start with any string from a list. This is what I am using for that:

^/(dir1|dir2|dir3|tmp|dir4)/

I'm also trying to match all paths that start with /tmp/ but do not contain special after that.

This should match:

/tmp/subdir/filename.ext

But this should not:

/tmp/special/filename.ext

I can't seem to find a way to get this done. Any suggestions would be greatly appreciated.

Try ^(?i)/(dir1|dir2|dir3|tmp(?!\/(special))|dir4)/.*

(?i) = Case insesitivity this will match SpEcial, SPECial, SpEcIAL etc.

(?!\/(special)) = Negative lookahead for the '/special'
