Hello Brian,

First of all, your script will not run, you forgot a closing quote on
the third line from the end.

But not to your problem. I was pounding over a similar issue recently
and the solution I came up with was to replace the for loop with a while
loop combined with a read command.

not working:
	for L in `cat inputfile`
	do
		echo "the line read is: ${L}"
	done

works fine:
	cat inputfile | while read L
	do
		echo "the line read is: ${L}"
	done

Cheers,

Kurt
