Another way of achieving it is running the script on screen
, if it is installed (usually is):
Then you can press ^A d (or in other words, hold CTRL, press 'a', release CTRL, press 'd') to detach the screen - it will continue running even if you log out, and whenever you want to get it back onto your display, run
The '-d' switch here isn't necessary unless the screen is already attached somewhere else, so you can leave it off if you know it's detached.
It depends on you then, which one is more comfortable for you.
