Kill Java Process – ‘kill java’ Command Not Working

killprocess-management

I am running debian right now and sometimes I need to kill java manually from the terminal, but when I try kill #pid# or pkill java nothing happens. No console output (ok, that's normal) and java is still running (not normal). The only way to kill it is to restart the PC.
Any suggestions?

Maybe its ignoring the signal for some reason. Did you try kill -9?

But please note: kill -9 cannot be ignored or trapped. If a process sees signal 9, it has no choice but to die. It can't do anything else - not even gracefully clean up its files.

Linux Kill Command – Kill Process Based on Arguments

pgrep/pkill take a -f flag. From the man page:

-f    The pattern is normally only matched against the process name.
      When -f is set, the full command line is used.

For example:

$ sleep 30& sleep 60&
[1] 8007
[2] 8008

$ pkill -f 'sleep 30'
[1]  - terminated  sleep 30

$ pgrep sleep
8008

Kill only one Java process

For killing a process that is associated with multiple processes, you need to kill that by using process id associated with that process.

To get the process id of that java process run

ps -A |grep java

output of this command will give the list of java processes running on your system. Note down Process ID (PID) of that process whom you want to kill and run

kill -9 PID
