This should be a simple one. I have a unix-formatted double spaced file, so each line of text is followed by 2 linefeeds, which is \n, right?

I want to run a perl script from the command line to translate double newlines to single newlines but it's not working. What is wrong with this code? 

perl -p -i -e 's/\n\n/\n/g;' foo.txt
