Htop 2.0 Released, Runs Natively On BSDs and Mac OSX
An anonymous reader writes: The popular Linux process viewer htop got a new major revision, and now runs natively on FreeBSD, OpenBSD and Mac OS X. The author discussed the process of making the tool cross-platform earlier this year at FOSDEM. Htop also got some new features, including mouse wheel support via ncurses 6 and listing process environment variables.
FWIW, I just installed it without incident on an instance of 10.6.8. That's pretty far back, and the site indicates there's at least some chance it'll work on even older releases.
