I want to use sed to look for spaces in text and when find one move the next word to the next line.

I used:

sed 's/ /\n/g' out > new

However when there is more than one space between two words it adds more lines between them. And I just want the words to be one under another. How can I change that?

Thanks

I find out how to do this:

sed '/^$/d'

However when I'm using emacs and put this two commands in one line they don't want to work:

#! /bin/bash
sed 's/ /\n/g' | sed '/^$/d' out > new

What I'm doing wrong???
