bash - Kuberntes kill process inside pod -

i using following code randomly kill processes inside pods

   : ${delay:=30}  if [ "$#" -ne 1 ];     echo "one argument expected specifying time in seconds run" else  end=$((seconds+$1))  while [ $seconds -lt $end ];   kubectl \     -o 'jsonpath={.items[*].metadata.name}' \     pods | \       tr " " "\n" | \       shuf | \       head -n 1 |       #xargs -t --no-run-if-empty \        kubectl exec $(head -n 1) -- kill -9 9   #if [ $((seconds+${delay})) -lt $end ];then            #break loop if (seconds completed + delay) greater time specified in argument   # sleep "${delay}"                                     #sleep pod gets deleted , terminating pod not selecte   #else   # break   #fi  done fi 

the script runs no output shown in goes infinite loop. can going wrong?

two things: -o 'jsonpath={.items[*].metadata.name}' should go after kubectl pods, otherwise kubectl return message. also, add -t kubectl exec in order see output container in terminal.
