Scheduling console commands


This is what it should look like, Send to console sends exactly what is in the Additional argument field to console, exactly as is. An example of what you could put into that field would be “say Hello” (without the “/” and without the parenthesis). Also it may help to check logs as it logs the commands that are input into the console how they are input into the console (so if something is being put in incorrectly you’d see it). Unknown command would typically mean something about the command is incorrect, so a log would help us to help you; I don’t know about the tellraw command and there seems to be lack of detail on it from lightly researching it, but I’m used to plugins like the Essentials family/bundle of plugins that let you use color in the say command as well as in other places like chat.

Based upon this that I found and read however, tellraw is not what you want or at least it does not seem to be what you want.

Syntax
    tellraw <player> <raw json message>

Arguments
    player
        Specifies the player(s) to send the message to. Must be a player name or target selector.

    raw json message
        Specifies the message to send. Must be valid raw JSON text (for example, {"text":"Hi there!","bold":true}).

Arguments - player - Specifies the player(s) to send the message to. Must be a player name or target selector.


Edit: perhaps maybe try these out and see how they go?

1: “tellraw @p ["",{"text":"JayMontana36's tellraw Sample Test Command 1","color":"red","bold":true,"italic":true,"underlined":true}]

2: “tellraw @p ["",{"text":"JayMontana36 tellraw Sample Test Command 2","color":"red","bold":true,"italic":true,"underlined":true}]
