Find duplicate lines and delete both lines

[53cricketballs]

Hello, I would like to know if textcrawler is able to find duplicate lines in a text file and delete both lines?

ie:

12345
12345
67890

would become

67890


TIA

You can use this providing the duplicate lines are next to each other:

Code: Select all

^(.*)(\r?\n\1)+$

Replacing with nothing will delete both lines.
