I suggest :

-----------------%><-------------------------------------

#!/bin/sh

cat foo.txt | while read LINE1
do
        echo 'One' > $$tmp
        cat bar.txt |while read LINE2
        do
                if [ "$LINE1" =3D "$LINE2" ]; then
                        echo 'ok' > $$tmp
                        break
                fi
        done

        if [ `cat $$tmp` =3D "One" ]; then
                echo "One !"
        fi

        if [ `cat $$tmp` =3D "ok" ]; then
                echo "ok !"
        fi
done
