You inspired to write a couple of scripts to generalise this process:
screen-run-program-in-region:
#!/bin/sh
eval "$*"
echo -n Press any key to close this region...
read throwaway_variable
screen -X eval 'focus bottom' remove
screen-open-region-with-program:
#!/bin/sh
screen -X eval \
"focus bottom" \
split \
"focus bottom" \
"screen screen-run-program-in-region $*"
Note that enabling zombie-mode will interfere with this script's
operation -- to kill the zombie window, screen-run-program-in-region
would need to also send Screen the 'kill' command. Unfortunately, if you
_disable_ zombie-mode then the 'kill' command would probably kill a
program that you _don't_ want killed. This is why we need a per-window
zombie-setting (*nudge* *nudge*). A way to silence the kill command
would also be nice.
BTW, I know that 'echo -n' is not portable. Please forgive me. You can
feel free to remove the '-n'.
