Try this:

-------------------------------------------
#! /bin/sh

awk '{
	print "echo '"'"'" $0 "'"'"' >> " $2 ".summary"
     }' | sh
-------------------------------------------

Only problem is, it tends to chew up process id's. Oh well ..... Also it
appends, so you might have a problem if you wanted to initialise at the
start of each run. But you get the general idea. Also has the advantage
of not getting into trouble if your input file hasn't been sorted (i.e.
$2 records can come in any order)
