It looks like as bash and its bug (I think). Internal command "time" in bash gives bad results (typically: user + sys > real). I even saw "user 0m:.230s" or so (with colon :-(((((((((((). Use "/usr/bin/time" instead - it gives better results... It is not problem on FreeBSD - I saw it on Linux too. Hey, I wrote bug report to bash developers after 2.0.1 release. But till now - no reply, no change. Send bug report to them too and wait... Or try to find bug (?). Good luck! (Grr. In "unzip -X ..." is bug too - do you know about this? :-) I have patch, but zip developers are the same as bash developers... Grr.) -------------------------------------------------------------------------- Rudolf Cejka E-mail: xcejka00@dcse.fee.vutbr.cz Technical University of Brno, Faculty of El. Engineering and Comp.
