The script that executes any batch job on the PCF as a task, waits for the result and prints out associated logs

task-wait.sh

#!/bin/bash

APP_NAME=$1
CMD=$2

task_id=$(cf run-task $APP_NAME "${CMD}" | grep "task id:" | awk '{print $3}')

task_name=$(cf tasks $APP_NAME | grep "^$task_id " | awk '{print $2}')
task_status=$(cf tasks $APP_NAME | grep "^$task_id " | awk '{print $3}')

while [ $task_status = 'RUNNING' ]
do
    sleep 1
    task_status=$(cf tasks $APP_NAME | grep "^$task_id " | awk '{print $3}')
done

cf logs $APP_NAME --recent | grep "TASK/$task_name"

exit $([ $task_status = 'SUCCEEDED' ])
