如何使用 git diff 比较两个不在存储库中的远程文件？

Question

我可以用 diff 和 ssh 比较两个远程文件:

diff <(ssh machine1 "sudo cat ${FILE}") <(ssh machine2 "sudo cat ${FILE}")

但如果我尝试 git diff，

git diff --no-index --color-words <(ssh machine1 "sudo cat ${FILE}") <(ssh machine2 "sudo cat ${FILE}")

我获得：

error: /dev/fd/14: unsupported file type
fatal: cannot hash /dev/fd/14

如何使用 git diff 比较不在存储库中的两个远程文件？

==更新==

这道题不是关于用diff和colordiff代替git diff，而是关于用git diff --no-index到ssh。

Answer 1

尝试使用

git diff --no-index <(ssh machine1 "sudo cat ${FILE}") <(ssh machine2 "sudo cat ${FILE}")

已找到 here。

Answer 2

由于 forgotten patch 而无法使用进程替换，唯一的选择（因为您想使用 git diff）是：

ssh machine1 "sudo cat ${FILE}" > temp1 
ssh machine2 "sudo cat ${FILE}" > temp2
git diff --no-index temp1 temp2

您可以使用 diff（它保持类似于 git diff 的格式和颜色）实现相同的效果，它也适用于进程替换

diff -u --color <(ssh machine1 "sudo cat ${FILE}") <(ssh machine2 "sudo cat ${FILE}")
