From fd297e33f553d9936d2c15728a417f0b7632ca52 Mon Sep 17 00:00:00 2001 From: Richard Stallman Date: Wed, 29 Jul 1992 04:44:02 +0000 Subject: [PATCH] Don't repeat the directory-link-chasing loop more than twice. Combine $prevdirs with $dirs--they had same value. Properly discard $d itself from the output of find.
