That maybe the case but does rm -f <file> remove all copies? Nope so its behaviour is safe even with multiple hardlinks. >From the description I've seen thats not the case for -P here and as such I dont think its quite a simple as that. My personal preference would be for it to warn or perhaps error if the link count is not zero. Possibly use -f to override this but even that I'd say is dangerous. ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
