Wait until a condition is met in bash script
提问by chandra
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.
这里循环永远不会退出，它会继续打印“自动化正在运行......”即使在自动化已经执行并且状态不是进行中我想要做的是等到状态为“进行中”，打印“自动化是运行......”在屏幕上。完成后，如果失败或成功，我想在屏幕上打印自动化的状态。

adding an if else until helped me get out of the loop.
添加一个 if else 直到帮助我摆脱循环。
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
