What confuses me is the tee. "tee -a" sends to a file, but your are doing a second redirection. I will have to test this later.

Nice :-) (I'll look at the link later, I have firefox "off" now, while I run an rsync live backup) Somehow, I find the implementation with named pipes "cute" :-) -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
