It doesn't have to. I fixed it. Stopping a job in a SOURCE'd file just stops the job. The shell continues with the next command in the file. My fix also means " a ; b ; c " behaves as documented; stopping process B lets process C start. -- -IAN! (Ian! D. Allen) University of Waterloo

I've often used ^Z to zap a series of type-ahead jobs, when that was what I wanted it to do. Especially useful if one of those jobs contains an error. You can use ^Z; fg to erase and start over again. That's the trouble, isn't it. One persons bug is another's feature. --elsie!mark -- Mark J.

Allen) University of Waterloo Great, Berkeley documents something as being a bug, later fixes it, and some person goes back and changes it back. In my opinion there are only two correct modes of operation for stopping a ; b ; c. Either the whole line should be stopped as a unit, or when b is stopped c should not be run. -Ron
