我希望使用tee将any command (first command)的输出写入一个文件，但我希望从first command而不是tee命令获得返回代码.
Example 1: The following code will return 1 and it is expected:个
cp -unknown-args "hello"
echo "return code is $?"
---output---
cp: invalid option -- 'k'
Try 'cp --help' for more information.
return code is 1
Example 2: The following code will return 0 and it is unexpected:个
cp -unknown-args "hello" | tee test.txt
echo "return code is $?"
---output---
cp: invalid option -- 'k'
Try 'cp --help' for more information.
return code is 0
如果first command有任何错误，我想把"Example 2"变成return 1.
这是可能的吗？如果是的话，该怎么做？
