Great idea. Love the minimalism! I was going to comment that it might be better (or at least easier to remember) to have short options like -o and -v instead of separate commands like dno and dnview, but then I looked at the code and noticed these are all just a collection of shell aliases stored in the "dn" file. Nicely done!
