How can I launch a program from a bash XTerm and run a while loop at the same time?
How can I launch a program from a bash XTerm and run a while loop at the same time?
I want to launch Oobabooga Textgen WebUI from the command line with its serial output. I also want to run a while loop that retrieves the Nvidia GPU memory available and temperature for display on the header bar with a 5 second sleep delay. How do I run both of those at the same time?

Indeed that works in the terminal to launch both my function and the application.
How would I do this inside a single function, like launch, then drop into the loop?
I'm having trouble understanding the question.
while true; do update-header-bar-or-whatever; sleep 5; done & oogabooga... will run the header update every 5 seconds, while oogabooga is running. Is that what you want?
If I launch like that it would stop at the oobabooga app launch until the job completed then it would resume the loop.
Ultimately, I'm doing more complex stuff and simplifying the question so it may seem slightly overkill to say I need it to work like this. I want to do some container checks, setup, and launch multiple applications with my own parsing flags and some conditional sourcing.
This only part I can't seem to grasp very well is how to run that little loop and update the header while other stuff launches with its serial terminal set to the same one the loop is running inside.
$ while true; do echo Hello, I updated the header; sleep 5; done & [1] 1631507 $ Hello, I updated the header sleep 30; echo Sleep is done. Hello, I updated the header Hello, I updated the header Hello, I updated the header Hello, I updated the header Hello, I updated the header Hello, I updated the header Hello, I updated the header Sleep is done. Hello, I updated the header $ kill %1 [1]+ Terminated while true; do echo Hello, I updated the header; sleep 5; done $Edit: I'm fairly confident now that you're just thinking the loop will stop when you run oogabooga, but that's not how it works. That up above is how it works; the loop keeps going during the sleep with them both going on the same terminal, then after the sleep process terminates, I kill the loop, but for the whole 30 seconds previous, they were both going. It'll be the same with oogabooga. This the situation you're asking about, yes?
If you're doing more complex stuff, maybe spend a few days learning the basics of bash
