I would have gone for 2 as well. What flavour are you using?

 

Debian. Didn't try it on another distro but most Debian commands are pretty usable in other distros. Does this not work in ubuntu?

EDIT: I just tried #2 on my Debian box. The command is not found for either the generic user or root user.
