@SbloodyS When we download binary packages and deploy them, we can use the bin/start.sh command to start the service without executing the bash bin/start.sh command. This is a common practice in most projects, such as start-dfs.sh, stop-all.sh, etc. in Hadoop

We do not recommend that users use these scripts directly. There are specific descriptions of starting and stopping using dolphinscheduler-daemon.sh in official website. https://dolphinscheduler.apache.org/en-us/docs/3.2.2/guide/installation/pseudo-cluster

So this modification is meaning less. Closing for now.
