That's because sudo is in /sbin (or, perhaps, in /usr/sbin, for the young'uns), which by default isn't in a regular user's PATH. That's all. That's not an "opinion" of Debian (I had that already in HP/UX around 1995 or so). Only if you try to do root-y things (change an interface's IP, for example) you'll need root privileges. Cheers -- t
