(I'm going through old bug reports that unfortunately weren't resolved at the time.) I can reproduce this, but I think that this works is more by accident than by design. I don't think the `&' command is supposed to allow any input to the command -- at least it's not documented to. In this example, you can type in stuff in the *Async Shell Command* buffer, and it'll append to 2.txt what you're typing, which is pretty eccentric behaviour for this command. Does anybody know whether this was intended? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
