osx terminal clear command queue

Question

I carelessly entered the up arrow followed by a return symbol while running a lengthy process in terminal. If I don't intervene the process will start over, clearing the results of the previous run. Is there any way I can clear terminal's command queue?

Answer 1

The "queue" may not have been read yet...

If the process (and shell) honor job-control, then you could try suspending the process temporarily ( control Z ) and resuming it (eg, %1 ). For this situation it is common (but not required) that on resuming the process the pending input on the terminal is discarded.
