Wait until a condition is met in bash script


until [ $(aws ssm get-automation-execution --automation-execution-id "$id" --query 'AutomationExecution.AutomationExecutionStatus' --output text) = *"InProgress"* ];
do
  echo "Automation is running......"
  sleep 1m
done
status=$(aws ssm get-automation-execution --automation-execution-id "$id" --query 'AutomationExecution.AutomationExecutionStatus' --output text)
if [ "$status" == "Success" ]; then
    echo "Automation $status"
elif [ "$status" == "Failed" -o "$status" == "Cancelled" -o "$status" == "Timed Out" ]; then
    echo "Automation $status"
fi

here the loop is never exiting, it keeps printing "Automation is running......" even after automation has been executed and status is not inprogress what i want to do is wait until status is " inprogress", print "Automation is running......" on screen. once its finished, i want to print the status of automation on screen if it failed or succeeded.


Solution

  • adding an if else until helped me get out of the loop.

    until [ $(aws ssm get-automation-execution --automation-execution-id "$id" --query 'AutomationExecution.AutomationExecutionStatus' --output text) = *"InProgress"* ];
    do
      echo "Automation is running......"
      sleep 10s
      if [ $(aws ssm get-automation-execution --automation-execution-id "$id" --query 'AutomationExecution.AutomationExecutionStatus' --output text) != "InProgress" ]; then
         echo "Automation Finished"
         status=$(aws ssm get-automation-execution --automation-execution-id "$id" --query 'AutomationExecution.AutomationExecutionStatus' --output text)
         echo "Automation $status"
         if [$status != "Success"]; then
            exit 3
            echo "Automation $status"
         fi   
        break
      fi
    done
