These tools often have a fallback mechanism which is less elegant and often make assumptions. I don't necessarily see this as "Unix" but rather as a powerful way of getting process/configuration info about the system. Anyhow, that's my input - I wouldn't care if it was/wasn't implemented personally - but I don't see how it "harms" the usability of Haiku by giving it another tool that other unix-like OSes already have. - Urias
