如何将AWS CLI的输出保存在变量中? [英] How to save output of AWS CLI in a variable?

问题描述

我想将一个AWS CLI的输出保存在一个变量中，并在另一个AWS CLI中使用该变量，如下所示:

I want to save output of an AWS CLI in a variable and use that variable in another AWS CLI, what I did is as follows:

taskarn= aws ecs list-tasks --cluster  mycluster --service-name "myService" --region "eu-west-1" --output text | grep "arn" | tr -d '"'

echo  $taskarn;  //empty
aws ecs stop-task --cluster mycluster --task $taskarn --region "eu-west-1"

当我回显$ taskarn时，它为空.

when I echo $taskarn, it is empty.

任何帮助将不胜感激.

推荐答案

我使用了以下命令，效果很好:

I used the following command and it works fine:

taskarn=$(aws ecs list-tasks --cluster  mycluster --service-name "myservice" --region "eu-west-1" | grep "arn" | tr -d '"')
echo  $taskarn;

aws ecs stop-task --cluster mycluster --task $taskarn --region "eu-west-1"
