System: NetBSD melanoma 1.1 NetBSD 1.1 (MELANOMA) #1: Thu Dec 7 12:45:12 EST 1995 root@melanoma:/usr/src/sys/arch/i386/compile/MELANOMA i386

>Description:
	GNU du supports '-c', which shows a grand total at the end. This is
	very useful when you do 'gdu -c -s *', amongst other things.
	This patch gives netbsd the same functionality.

>How-To-Repeat:
	run du. notice lack of grand total option.

>Fix:
	apply this simple yet effective patch.
