    NodeJS bloated crap just to kill a process?

    Ever heard about htop? More functionalities and less boatware…

    But if I want to get out of Fkill deciding not to terminate processes??? I’m missing key

  3. Jim says:

    How is fkill better than pkill?

    • Aaron Kili says:


      It allows you to kill processes interactively, you can get a full list of processes, and use UP or Down arrow keys to select processes, then press enter to kill a process.

  4. Jo says:

    Easy alternative using fzf (does not require nodejs).

    # ps -eaf | fzf | awk '{print $2}' | xargs kill
