You can use if statements to key off of the return code of a command. You could do something similar to the following:

if ! cmp <file a> <file b>; then
echo "pass!"
fi

If I understand correctly, you want to return "pass" if all the lines of cmp1 are in cmp2, and you don't care if cmp2 has some extra lines. If so, then try...
Code:
[[ $(comm -23 cmp1 cmp2 | wc -l) -eq 0 ]] && echo pass
