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
