Actually, it occurs to me that there's a simpler approach, which might sometimes be wiser - arrange for standard input to be something other than the keyboard. For example, under unix:
:|jconsole -js 'echo 1+1' You'll get a prompt before the exit, but you can avoid that with an explicit exit statement: :|jconsole -js 'echo i.3 3' 'exit 0' Under windows this can be a bit uglier: echo ] >blah.txt jconsole -js 'echo i.3 3' < blah.txt So... why is this a good idea? Well, a problem with using something like "9!:29]1[9!:27 'exit 1'" is that this suppresses the display of any error messages. By instead specifying an empty (or nearly empty) file as standard input, you get to see the error message and stack trace. And you should not care if the display looks a bit messy under error conditions - your real concern should be in alleviating the error. (But if you want an error exit code, you might still want to use some variation on the other approach...)
