lr is a compliment of ls.
lr lists directories recursively.
You will say we have an equivalence:
	du $target | awk '{print "ls -l",$2}'|rc
Yes, using
	du + ls
gives good recursive option to ls.
However I dislike the date format of ls.
That is rather for human reading.
I prefer date field something like
	2003/07/30 06:35:53
that is familiar to us Japanese and easy to handle by machine.
