Safely kill all anoying processes (chrome for example :))

kc.sh

#!/bin/bash
[[ $1 == '-x' ]] && { export TRACE=1; shift; set -x; }

proc=${1:-chrome}

declare -a pids
declare -i c=-1
while pids=($(pgrep $proc)); do
        kill ${pids[@]}
        (( c++ )) || {
                bash <<'EOSH' &
sleep 3
kill $PPID
[[ -d /proc/$PPID ]] && {
        sleep 0.02; 
        [[ -d /proc/$PPID ]] && kill -9 $PPID
}
EOSH
                childPID=$!
        }
        sleep 0.01
done

[[ $childPID && -d /proc/$childPID ]] && \
        kill -9 $childPID
