在git show commit中，/ dev / null有什么意义？ [英] What's the significance of /dev/null in a git show commit?

问题描述

--- / dev / null 通过 git show commit 输出表示

这是一个新文件的添加，因此我假设它没有删除任何内容，但为什么引用 / dev / null
$ $ $ $ g $ show a395a

我的第一次提交。

diff --git a / test.txt b / test.txt
新文件模式100644

+ Hello


解决方案

这意味着，因为test.txt是一个新文件，所以在显示的diff中将其与nothing进行比较。 file/ dev / null。

What does the --- /dev/null signify in by git show commit output?

This is an addition of a new file, so I assume it's saying that nothing was removed, but why the reference to /dev/null?

    My first commit.

diff --git a/test.txt b/test.txt
new file mode 100644
index 0000000..e965047
--- /dev/null
+++ b/test.txt

+Hello

解决方案

It means that because test.txt is a new file, in the diff shown, it was compared to "nothing"; the "file" /dev/null.
