Note that many of the service scripts use a cacheing mechanism to avoid hammering their respective data sources. Caches are stored in the same directory as the script, so you'll want to ensure that directory isn't read-only.

$ bbrss.py <source/rssurl>

$ bbweather.py <zipcode>
Prints out a brief forecast. Edit the "numdays" variable to change the length of the forecast.
$ cmdrepeat.py <delay (minutes)> <command arg arg ...>
Unlike the above service scripts, this utility script isn't meant to be run by bbusb. Instead, it's meant for repeatedly running bbusb (and updating your sign) with a set interval, without needing to set up a cron job (or similar). For example, running "cmdrepeat.py 1 bbusb -u config.txt" will update your sign once a minute using the provided config file.
