Hello, I'd expect
window -hide rc -c 'label a_name; tail -f some_file' would create a new hidden window (and so it does), run the tail command (and so it does) and set the name for the hidden window to a_name. The last thing seems to not happen (at least from the viewpoint of using the button-3 menu in rio --- I only see an empty field, i. e. without any name). Can anyone tell me what's wrong? Thanks Ruda
