Author: keramida (doc committer) Date: Thu Jan 15 03:48:49 2009 New Revision: 187272 URL: http://svn.freebsd.org/changeset/base/187272 Log: 176561 | keramida | 2008-02-25 21:06:43 +0200 (Mon, 25 Feb 2008) | 11 lines 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.
