Gerrit from the blog Sustainable Research posted a nice article about the screen-command for the linux console that allows you to run scripts in the background without an open console window. This can be also useful, when you want to run SPM-scripts without a user interface and remote on a server. You just start the script within a screen, exit the screen and close the remote connection. And with Putty for Android or iPhone you can supervise your scripts from everywhere :).
