If I just run 'time rpm -qa' then about 15 files appear and then this file appears gpg-pubkey-1cddbca9-3f9da14c after this, the output stops for quite a while (with no real activity on the CPU) then lots of output and then another stop after gpg-pubkey-db42a60e-37ea5438 gpg-pubkey-30c9ecf8-3f9da3f7 quite a pause in proceeding, again with no notable CPU usage) and then lots more files (the sort of output I would expect from rpm -qa) and then it finishes. The time info from this is: real 6m41.756s user 0m3.245s sys 0m0.612s so I think we can assume that the grep doesn't have anything to do with this. I suspect something is up with the files listed above. Rodd
