如何在AWS CLI输出中循环显示? [英] How to I loop through AWS CLI output?

问题描述

我正在尝试将aws cli查询的值列表传递给另一个命令.即使我在AWS中看到了很多示例，当我尝试将所有值组合在一起时:

I am trying to pass a list of values from a aws cli query to another command. Even though I have seen plenty of examples in AWS, when I try all the values come together:

  policy_versions=`aws iam list-policy-versions --query "Versions[].VersionId" --policy-arn $POLICY_ARN --output text`
  echo "policy_versions=$policy_versions"
  for ver in $policy_versions; do
    echo "first version: $ver"
  done

然后打印出来:

policy_versions=v3  v2  v1
first version: v3   v2  v1

我的 ver 值是整个字符串，应为 v3 ，然后为 v2 和 v1 .而是: v3 v2 v1 .

My value of ver is the entire string, it should be v3 then v2 and v1. But It is instead: v3 v2 v1.

我不知道怎么了.

推荐答案

我能够重现您的结果，并且将结果追溯到shell和 zsh (现在用作是MacOS中的默认外壳).

I was able to reproduce your results and I traced the results to a difference between shell and zsh (which is now used as the default shell in MacOS).

简单地输入，您可以运行此命令以使其按预期的方式工作: setopt shwordsplit

Put simply, you can run this command to make it work the way you expect: setopt shwordsplit
