That crazy old wizard just typed grep . ./droids.txt | grep -v r2-d2 | grep -v c-3p0!

Grepping for any symbol (.) is not a very meaningful thing. I guess he just wanted the list of droids without r2-d2 or c-3p0 in their lines. That could be achieved by just using egrep or grep -E: grep -vE r2-d2|c-3p0 < droids.txt. Or, more conventionally, sed: sed '/r2-d2\|c-3p0/' < droids.txt
