Beautiful, nuts' I just presumed I needed to grep for that. Much faster your way. As for awk, I don't know anything about it, but googling for help on various issues, one sees awk coming to the rescue all the time. I half way learned sed, but I think I should have learned awk. One little thing, can I have the first and last columns, but with a tab between, or some other columnizer?:Running lsof | grep seems a bit silly. Can't you just do lsof $mountpoint?
When I want to select columns I usually reach for awk:
sudo lsof $mountpoint | awk '{print $1, $NF}'
