Hi,
Ok, I found my very quick, dirty and non-functional example shell script
printing out an ordered list of saved ConnMan services. It most likely
won't work properly or at all, so someone should definitely fix it with
better shell syntax and usability if considered for any real world use.
It of course uses internal information from save files and will break
the very moment ConnMan makes changes to its internal behavior.
Cheers,
Patrik
