 ## Logging to a file
@@ -44,15 +44,7 @@ To send logs to a file, you can redirect the stdout logs:
 
 ```
 # log json to filename.jsonl

 We recommend keeping an eye on the growth of this file with a [log rotator](./log-rotate.md). Logs are written in the "JSON Lines" format - one `json` entry per line.

-Nimbus also supports writing logs to a log file using the `--log-file` option - this is provided for historical reasons and may be removed in future releases.

-```
-./run-mainnet-beacon-node.sh --log-file=filename.jsonl # write json logs to the given filename

-When the `--log-file` option is enabled, stdout logs will by default be disabled. You can enable them with the `--log-stdout` option (choose any format other than `auto`).
