Which Chia plot file found the proof?

How to find the Chia plot file that won the block?

1. Search your receive address on Chia Explorer
2. Scroll down the page to look at your farmer rewards
3. Click on the reward for which you want to find the plot
4. On the page that comes up, click on the Confirmed block index number
5. Scroll down to find the proof_of_space.plot_public_key and copy the key

On your harvester/full node run the following command at the command prompt:

curl --insecure --cert ~/.chia/mainnet/config/ssl/harvester/private_harvester.crt --key \
~/.chia/mainnet/config/ssl/harvester/private_harvester.key -d '{"":""}' \
-H "Content-Type: application/json" -X POST https://localhost:8560/get_plots | python3 -m json.tool

If the command succeeds, it will display information about all of your plots. You can use grep to find the file name for the winning plot. Replace the <plot-public-key> with the key that you copied from the step 5 above in the following command:

curl --insecure --cert ~/.chia/mainnet/config/ssl/harvester/private_harvester.crt \
--key ~/.chia/mainnet/config/ssl/harvester/private_harvester.key -d '{"":""}' \
-H "Content-Type: application/json" -X POST https://localhost:8560/get_plots | \
python3 -m json.tool | \
grep -A5 -B4 <your-plot-public-key>

so what happens with multiple farmers winning a block?

I think this needs updated?
