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?:
