Excuse me - I made a mistake! Of course those two lines
have to be:

cat /foo/bar.txt | while read LINE1

and

	cat /foo/bar/foo/bar.txt | while read LINE2

The $ infront of the variable names have to be removed.
The variable _name_, not its content, has to be provided
to "read" as a parameter.

The script so far:



#!/bin/sh

cat foo.txt | while read LINE1
do
	cat bar.txt | while read LINE2
	do
		if [ "$LINE1" = "$LINE2" ]; then
			sw="1"
			echo "Current value of sw is : " $sw
			break
		fi
	done
	echo "Value of sw is : " $sw
	if [ "$sw" = "0" ]; then
		echo "DO SOMETHING!"
	fi
	sw="0"
done
