管git diff到git應用

Question

為什么這個命令不起作用？

git diff | git --git-dir=/other/location/.git --work-tree=/other/location apply

以下工作完美：

git diff > /tmp/my.patch
cd /other/location && git apply /tmp/my.patch

/other/location是當前目錄的鏡像。

通過管道命令，我得到了

error: patch failed: myfile.php:1
error: myfile.php: patch does not apply

Answer 1

這對我git 2.6.3 （ git 2.6.3 ）：

git diff | git -C /other/location apply

來自man git ：

-C <path>
       Run as if git was started in <path> instead of the current working
       directory. When multiple -C options are given, each subsequent 
       non-absolute -C <path> is interpreted relative to
       the preceding -C <path>.
