I have an app controlling a piece of connected hardware that displays a few lines of info and requires user input (on stdio). The app runs fine from a shell.
I set up the RPi to auto-login with CLI and run the app as a cron job shortly after reboot. It runs (as evidenced by it interacting properly with the attached hardware) but I cannot see the output and there is no way to enter input; it's running in the background, not interacting with the open shell.
How can I make it interact with the open shell, or start a new one?
