CodePudding user response：

You can use

^YZ[ABC].*NUM12345.*

See the regex demo:

If you want to remove all lines other than the ones that match the above pattern, you can use

^(?!YZ[ABC].*NUM12345).*\R*

See the regex demo:

Details:

^YZ[ABC].*NUM12345.* - start of string, YZ, A / B or C, then any zero or more chars (other than line break chars) as many as possible, NUM12345 and then any zero or more chars (other than line break chars) as many as possible.
^(?!YZ[ABC].*NUM12345).*\R* - start of string, then a negative lookahead that fails the match if the above pattern is matched, and then any zero or more chars (other than line break chars) as many as possible and then any zero or more line break sequences.
