Shell script to stop a java program

Question

Is there a way to stop a java program running using a shell script by knowing the name alone.I am using ksh shell

Answer 1

You can use pkill:

pkill your_java_program_name

This would work if you run only one instance of the your program is running.

Answer 2

You can use jps identifying the process-id associated with the name of the started java-program (jps is a process-manager for java-programs). With this id you can kill the process normally.

Answer 3

Add a unique property to the JVM to identify it easily, e.g. for test.class

java -Duniquename=1 test

To kill it:

ps ax | grep uniquename | grep -v grep | awk '{print $1}' | xargs kill

Answer 4

following up on Mnementh' suggestion:

this should do the job

jps -l | grep org.example.MyMain | cut -d ' ' -f 1 | xargs -n1 kill

• jps -l: list java process with "full package name for the application's main class or the full path name to the application's JAR file."

• grep: choose the process you like

• cut -d -' ' -f 1: split the output in columns using delimiter ' ' and print only the first one (the pid)

• xargs -n1 kill: execute kill for each PID

note that you must run jps and xargs with the same user (or root) as you're running the process

Answer 5

you can use -o option of ps to format your output,

ps -eo cmd,pid | awk '!/awk/&&/mycommand/{cmd="kill -9 "$2;system(cmd)}'
