To identify the running Java binary for the Jenkins service on a Linux system, the ps (process status) command is used. The -aux flags provide a detailed list of all running processes for all users in a user-oriented format.

This allows the user to isolate the Jenkins process and inspect its details, including the full path to the Java executable that is running it.
