Robert,
That's not what I meant - I know I can use "time" to get CPU usage
information.
I was meaning that I don't get the disk speed summary like Nicola did, e.g.:
me@beast:$ dd if=/dev/zero of=/storagearray/test.tmp bs=4096
1238865+0 records in
1238864+0 records out
5074386944 bytes transferred in 63.475536 seconds (79942404 bytes/sec)
