I've been messing around with command blocks recently, and I need to be able to 'log' my command block output.
I can see the last output it had
'Gave 1 diamond to JackOBoi04' (example)
but I am trying to find a way to take said output, and log it in a book, or something like so even when I'm offline, when I come back online I can look back at the list of said command block's output, from when I was offline.
You can't. Besides for a simple succeeded or failed, you cannot read output from a command block.
Perhaps you could use the /clone command to clone a ton of different command blocks so you can go and look through all the copies but that is pretty unreasonable.
/cloneing the command block will keep its data, so I just meant copy it to a storage spot and have it never run
If you construct your command blocks to increment a scoreboard its a form of logging:
/scoreboard objectives add diamond
/scoreboard players set diamond diamond 0
The above commands creates a scoreboard objective 'diamond' then sets a fake player's score to 0 (as long as the name doesn't match the name of someone on the server you can make as many fake players as you want).
At the end of a chain of command logic, you could put the following command to 'log' the example you gave.
/scoreboard players add diamond diamond 1
Then when you want to view the results you could list the objectives of your fake player
/scoreboard players list diamond
