First, I've redone the patch at multiple requests to eliminate the wildcards. It's been pointed out that "rm -rf *" isn't a good thing to recommend. Under earlier versions of FreeBSD, some files in /usr/obj were marked noschg. A user could use your example to delete the tree if he didn't care about the errors. Under newer versions of FreeBSD, /usr/obj has no schg files. The first rm -rf will delete the whole tree, and the other commands will either generate errors or have no effect. I'm trying to write a single entry that covers all versions of FreeBSD. More experienced readers will easily understand that we're telling them to remove /usr/obj/usr by any means necessary, and will use their preferred method to do so. ==ml -- Michael Lucas mwlucas@blackhelicopters.org http://www.blackhelicopters.org/~mwlucas/ Big Scary Daemons: http://www.oreillynet.com/pub/q/Big_Scary_Daemons To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the messagehelp
