But according to the man page, the xterm window will remain open all the time, not just when the subprocess terminated with a non-zero exit status. Also, I suppose that this doesn't solve the problem when xterm is run on a remote machine and output on the X server of the local machine: if the remote machine shuts down or the X connection is lost (e.g. due to a network problem), the window will disappear. > There's nothing implemented to "save its data", though that could be > done in principal by reusing the logic for printing the screen, > e.g., to save the scrollback as a file.

Well, I meant that the exit hook should have access to the exit status of the subprocess if available (the other case is when xterm terminates abnormally, e.g. by receiving a signal like TERM or HUP or due to lost X connection, one should also be able to save the data). > >> * when the X connection has been lost (it is not possible to keep > >> the xterm window open, but it should be possible to save the > >> terminal data and do some clean-up if need be). > > Here, "some clean-up" is vague (I suppose that's whatever is done in the > hypothetical script to which xterm would transfer the saved data).
