I would like to delete all lines that start with a
\, but I am not sure how to go about it. I searched online but still there seems to be some piece missing. I tried to use regular expression.
But it doesn't work. I think I need to double quote the patten, but it still doesn't work. Vim replied with an error of pattern not found.
