Stop the right export

Two exports run on the server under another account. One has to be stopped so that it saves its work, and the other must be left alone. You choose the commands.

Both are the same export program as at the start of the lesson: asked to exit, it finishes its report and only then exits. Do not stop the other one, not even with a pause, and do not restart it: the check recognises it by its start time.

The March export

Two export runs work on the server as www-data, one for March and one for April, writing their reports to /srv/export. Stop the March one so that it saves its report. Let the April one keep running.
