Details:
I developing on a software operation state indicator in my .screenrc as a
backtick. The software uses ROS PUB/SUB so I would like to run the backtick
program in the background and have the indicator update when the operational
state changes. According to the docs:
"If both the lifespan and the autorefresh parameters are zero, the backtick
program is expected to stay in the background and generate output once in a
while. In this case, the command is executed right away and screen stores the
last line of output. If a new line gets printed screen will automatically
refresh the hardstatus or the captions."
I noticed that this background backtick program does not exit when screen
exits. Is that working as intended or is that a bug?
Let me know if you need me to provide more specific information for
reproducing this bug.
