tput help

[Eben King <eben@gmx.us>]

A while back I wrote a script to take the output of dd and make a graph 
of the transfer rate.  It worked, but since it scrolls up I wasn't happy 
with it.

In a bash script, I'm trying to use tput commands to delete column 1 
(tput cup $row 1 && tput el1), scoot the rest of the line left, then 
draw along the right edge (echo -n).  Step 2 is proving problematic, as 
in I don't know how to do it.  Is there another way?  Thanks.
