JPS Tools

The JPS (Java Virtual machine process Status Tool) is a command that JDK 1.5 provides to show all current Java process PID, and is simple and practical, ideal for linux/ Simple view of the current Java process on the UNIX platform.
The JPS (Java Virtual machine process Status Tool) is a command that JDK 1.5 provides to show all current Java process PID, and is simple and practical, ideal for linux/ Simple view of the current Java process on the UNIX platform.

I think a lot of people have used the PS command in the UNIX system, which is mainly used to show the current system's progress, which processes, and their IDs. JPS is also the same, its role is to display the current system of Java process, and its ID number. We can use it to see how many Java processes we've started (because each Java program will monopolize a Java Virtual machine instance), and their process number (to prepare for the following programs), and opt to see detailed startup parameters for those processes.

How to use: Hit JPS under the current command line (need java_home, no words, to the directory to change the program to play).

JPS stored in the JAVA_HOME/BIN/JPS, when used for convenience please add java_home/bin/to path.
