How do I get the server to execute a command and render the result in the chat bar?

As the title says. The script looks like this: Using runCommad() to ask the server to execute a command that the average player doesn't have access to, I had to ask the server to execute or else I had to turn on the cheat. This command /checkspawns legendary is used to query the legendary mobs refresh time in the Pixelmon Mod, whereas runCommad() only return 1 and 0. I can't get the details of the output of the server console. So even if I render the chat bar with tell(), it's just telling me a 1 or 0. How can I get the information of the console? Or do you have a better idea?

You would have to look at the code the command is calling and replicate that using some reflection.

Commands return a number as a redstone output for command blocks and if it failed or not (0 failed, 1-15 redstone). The actual output is basically just chat messages.
