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'.
