Alias: v5x r run accepts the same --slot, --name, --description, --icon, --file, --no-build, and --port options as upload. It always asks the brain to start the uploaded program.
Add -t, --terminal to keep the connection open and stream the program’s output as soon as it starts, so nothing it prints at startup is missed:
See terminal for the streaming options and how to send input back to the program.
