How to prevent sqlcmd truncation with for xml path query result

I ran into the same issue today, I used the -y0 option. My output looks correct now. Thought I would post my findings so it might help others running into the same thing.

sqlcmd -Sxxxxxxx -E -dmaster -h-1 -y0 -Q" my query that produces long results in here;" > "D\:out.txt"

-h-1 removes the column headers too.
