Fix Double Space file - Delete every other line?

[othni]

What would be the best way to fix a file that, for some reason, was written with a blank line every other line.

I am thinking of using the Remove Blank lines filter.

Is that the best way?

Yes. I thought that would be obvious!

Is not the same to remove all blank lines than to remove every other line (that just happen to be bank).

There maybe blank (valid) lines that I do not want removed.

If there are two blank lines together, only one should be removed.

Sorry! I see what you mean.

You can remove blank lines by doing an EasyPattern search replace like this:

[ capture( 0+ not cr or lf ), cr lf,
cr, lf ]

Replace with:
