Do you want to find double linebreaks only or atleast double? –  amiregelz Dec 12 '12 at 9:37

If you use "regular expression" search mode:

(\r\n\s*$){2,}

Will find all instances of 2 or more blank lines, including ones that just have spaces on the line.

E.G. using a replace of \r\n

something



something else



another thing

Another








Another thing

Becomes

something

something else

another thing

Another

Another thing

To find double or more linebreaks (and ignore single linebreaks), search in Extended Mode for the following expression:

\r\n\r\n\r\n

It will match this case:

line a


line b

but not this one:

line a

line b

If you want to search and replace, you need to modify the expression a little bit.

Press Ctrl+F, select extended search mode and search for \r\n\r\n.
