I modified it like this:

                        echo "alg $alg"              
                        echo "key $key"
                        echo "comment $comment"
                        printf "$alg $key $comment\n" >> "$keyfile" ; \


so I could see where printf was breaking. It's breaking on the first one
-- $alg

key: Undefined variable.
comment: Undefined variable.
