Bash scripting to determine between two terminals which one is in control.

jefsa · 12-09-2020, 12:07 PM

Hello,

OS is Slackware 14.1

I am using bash scripts to communicate between two terminals and running scripts.

What command(s) can I use to tell which terminal is in control.

The goal is to let the other terminal, not in control, know that the other has executed the
loading of a configuration. Using this information it can then update its files two match
the one in control.

Thanks.

Or write a script that runs something in a subshell, return when it's done, and continue on. Variables won't exist in another subshell. You can have a variable in the parent process.

I was similarly flabbergasted but didn't dare to voice it; in any case, please OP, explain in full detail what problem you are trying to solve and not what you think might be a solution: https://xyproblem.info/

Named pipes?
