How to kill all processes younger than

  • 772

I know for killall command with -y argument and process name.
But I need command to kill all processes younger than some time, without knowing their names. Something like: 

killall -y 20m *
command-line killall

  1. Use:

     killall -y 5m -i -r ".*"

    Or use a combination of ps and kill:

    kill $(ps -eo pid,etimes | awk '{if ($2 < 300) { print $1}}')

    First we find the id of process that are running less than of 5 minutes using:

    ps -eo pid,etimes | awk '{if ($2 < 300) { print $1}}'

    Then we kill them using kill.

    Base of command comes from here.
