Hi all,

I want to do the following.

1. Search a keyword in a file
2. Mark all the lines that contains this keyword.
3. Delete all these lines.

I know some other tools allow users to mark all the lines that contain a specific keyword, then users can delete all the marked lines.

Can EmEditor do it?

Thanks.

I guess it can be implemented with find & replace using regular expression, but I'm not good at it.

Could easily be done with regular expression.

Could search for:

and replace with nothing. That should remove all lines that contain the word "keyword". Just change "keyword" into whatever you would like to search for.
