so you'll have to do, for example, {"name":"grab 1 video now", "shell": "bash grab1vidnow.sh"}
but the way I did that, I have to split up and rejoin the spaces... so now when you send it args, i'm adding a space.
old and busted:
{"type": "gray_messages.directorial.execute_command", "command":"grab 1 video now", "args": " https://www.youtube.com/watch?v=OnNyPS2iaLo"}
new hotness:
{"type": "gray_messages.directorial.execute_command", "command":"grab 1 video now", "args": "https://www.youtube.com/watch?v=OnNyPS2iaLo"}
