Find Process ID

For me this is divided into these use cases.

Find Process Listing on Port

lsof -i :3000 #find processes listing on port 3000

Find Java Process

For Java processes there is jps. Which can be used as:

• jps: list all JVM processes
• jps -q: list all JVM processes with only PID
• jps -m: display the arguments passed to the processes
• jps -l: display the full package name of all processes
• jps -v: Display the arguments passed to the JVM
