New Revision: 187276
URL: http://svn.freebsd.org/changeset/base/187276
Log:
MFC 176561
Implement from scratch a -l option for du(1), to match the same option
of the GNU utility. The default behavior of our original `du' is to
count hardlinked files only once for each invocation of the utility.
With the new -l option they count towards the final size every time
they are found.
