庆典：重定向（并附加）输出和错误到文件终端和得到适当的退出状态 [英] bash: redirect (and append) stdout and stderr to file and terminal and get proper exit status

问题描述

要重定向（和app​​end）输出和错误到一个文件，同时在终端上显示出来，我这样做：

To redirect (and append) stdout and stderr to a file, while also displaying it on the terminal, I do this:

command 2>&1 | tee -a file.txt

然而，有另一种方式来做到这一点，这样我得到的退出状态的精确值？

However, is there another way to do this such that I get an accurate value for the exit status?

也就是说，如果我的测试 $？，我想看看命令的退出状态，而不是 T恤的退出状态。

That is, if I test $?, I want to see the exit status of command, not the exit status of tee.

我知道，我可以使用 $ {PIPESTATUS [0]} 而不是 $？在这里，但我要寻找，不会有涉及检查另一种解决方案 PIPESTATUS 。

I know that I can use ${PIPESTATUS[0]} here instead of $?, but I am looking for another solution that would not involve having to check PIPESTATUS.

推荐答案

也许你可以把从PIPESTATUS退出值到 $？

Perhaps you could put the exit value from PIPESTATUS into $?

command 2>&1 | tee -a file.txt ; ( exit ${PIPESTATUS} )
