ps -ef | grep [f]oo | awk '{print $2}' | xargs kill -9

kill all foo process

Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command. Works on almost every Linux/Unix platform I have tried.

  • You cannot kill zombies, as they are already dead. But if you have too many zombies then kill parent process or restart service. You can kill zombie process using PID obtained from the above command. For example kill zombie proces having PID 4104: # kill -9 4104 Please note that kill -9 does not guarantee to kill a zombie process.

  • Well this can come handy , when you don't feel like playing with pid rather if you know the process name say "firefox",it would kill it.The script given below would kill the process with its name given as first parameter , though not robust enough to notify that process doesn't exist , well if you know what you are doing that's wouldn't be a problem.:) ---- killhim.sh ---- #!/bin/bash ps -u $USER |grep $1 | awk '{ print $1}'| xargs kill ----

  • Kill -9 immediately kills the given process number. $$ is the process ID of the process you are in.

    kill -9 $$

  • This command kills all processes with 'SomeCommand' in the process name. There are other more elegant ways to extract the process names from ps but they are hard to remember and not portable across platforms. Use this command with caution as you could accidentally kill other matching processes! xargs is particularly handy in this case because it makes it easy to feed the process IDs to kill and it also ensures that you don't try to feed too many PIDs to kill at once and overflow the command-line buffer. Note that if you are attempting to kill many thousands of runaway processes at once you should use 'kill -9'. Otherwise the system will try to bring each process into memory before killing it and you could run out of memory. Typically when you want to kill many processes at once it is because you are already in a low memory situation so if you don't 'kill -9' you will make things worse

  • Find and kill multiple instances of a process with one simple command.

    pgrep rouge-process | xargs sudo kill -9

  • Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.


    -2
    ps -ef | grep APP | awk '/grep/!{print$2}' | xargs -i kill {}

What Others Think

You don't need the grep, awk can do this for you: awk '/foo/ && ! /grep/ {print $2}'

Don't forget, if you have processes that do not belong to the current user, you need to sudo the xargs command.
