bash等待开放完成

Question

I just asked a question here and it made me think of another. Is is possible to get an exit code from whatever editor is opened from the bash command

open -t ...

It would be great if i could perform an action after the user had exited the text editor (and also work out if they saved the document while it was open). Is this possible?

Answer 1

Do you really want the exit code, or just confirmation that the user has exited the text editor? The -W option causes open to wait until the editor exits before exiting itself. The value of $? would be, I suspect, the exit code of open , not the editor. Since the editor likely is a child process of launchd , not your shell, I'm not sure how you retrieve the exit code of the editor.
