Git 如何检查bash脚本中的空樱桃选择？

我有一个bash脚本，它运行以下cherry pick命令：

if git cherry-pick -x "$commitId"; then
        ammed_commit "$BRANCH" 
  else
      #here I want to check if this resulted in empty commit
fi

我尝试再次运行该命令并以字符串形式获取输出，然后比较字符串，但输出不是我在控制台中看到的。我正在使用以下脚本进行测试：

#!/bin/bash

READ_STATUS=$(git cherry-pick -x 001e6beda)
SUB_STRING="The previous cherry-pick is now empty"

echo $READ_STATUS

stringContain() { [ -z "${2##*$1*}" ]; }

if stringContain "$READ_STATUS" 'The previous cherry-pick is now empty';then 
  echo yes
else 
  echo no
fi

exit

下面是我运行此脚本时收到的输出：

The previous cherry-pick is now empty, possibly due to conflict resolution.
If you wish to commit it anyway, use:

git commit --allow-empty

Otherwise, please use 'git reset'
//READ_STATUS gets this value and not the one above this line???
On branch test-stage Your branch is ahead of 'upstream/test-stage' by 1 commit. (use "git push" to publish your local commits) You are currently cherry-picking commit 001e6beda. nothing to commit, working tree clean
no

所以我有两个问题：

为什么我的字符串没有得到完整的输出

如何解决此问题并成功检查cherry pick是否导致空提交

git

将其错误消息发送到stderr，而不是stdout

READ_STATUS=$（git cherry pick-x 001e6beda）

捕获标准输出，并在git失败时将READ_STATUS设置为nothing

您可以通过以下方式重写代码：

read_status=$(git cherry-pick -x 001e6beda 2>&1)
empty_message="The previous cherry-pick is now empty"
if [[ $read_status = *"$empty_message"* ]]; then
  echo yes
else
  echo no
fi

谢谢。很好用！
