Use cmdj instead of cmd

[Maijin]

Hello o/,

Just a quick note, when you retrieve information from commands such as fs, o etc. Strongly recommened you use cmdj and the json equivalent command (fsj, oj etc.) instead of parsing the output manually and risk that your script breaks when a new display of the command is out!
