This was discussed on wine-devel some time ago, and the conclusion was that no one should ever want this. Not even developers. A suggestion made to Dan was to use this: $ WINEDLLOVERRIDES=mshtml= wine cmd /C echo test For running cmd. This disables mshtml though. Wine without gecko is considered as a broken wine install, so I don't know why you wouldn't want to put gecko somewhere on your hard drive. P.S. I'm kinda drunk, so I probably shouldn't post this, because it can contain total crap, but I'm just trying to help you out.
