检测 Git 工作区中已修改文件的简单方法是什么？
在 make 过程中，我创建了嵌入链接输出中的字符串字段。非常有用。
除了复杂的 sed/grep 解析 git status 命令之外，我如何轻松确定工作区中的文件是否已根据git ？
During make, I create string fields which I embedded in the linked output. Very useful.
Other than a complex sed/grep parsing of the git status command, how can I easily determine if files in the workspace have been modified according to git?

如果您只想要一个简单的“与 HEAD 有什么区别吗？”：
如果退出代码为 0，则没有区别。
如果您想要“哪些文件从 HEAD 发生了更改？”：
如果您想要“哪些文件从 HEAD 发生了更改，以及它们以什么方式更改（添加、删除、更改）？”：
添加
-M（和-C）如果您想要重命名（和复制）检测。这些命令将检查暂存的内容（索引中的内容）和工作树中的文件。像 git ls-files -m 这样的替代方案只会根据索引检查工作树（即它们将忽略工作树中的任何暂存（但未提交）内容）。
If you just want a plain “Are there any differences from HEAD?”:
If the exit code is 0, then there were no differences.
If you want “What files have changed from HEAD?”:
If you want “What files have changed from HEAD, and in what ways have they changed (added, deleted, changed)?”:
Add
-M(and-C) if you want rename (and copy) detection.These commands will check both the staged contents (what is in the index) and the files in the working tree. Alternatives like
git ls-files -mwill only check the working tree against the index (i.e. they will disregard any staged (but uncommitted) content that is also in the working tree).来自 git help -a ：
From
git help -a:git status --porcelain 似乎提供了一个很好的可解析输出。
git status --porcelainseems to give a nice parsable output.对于 git hooks，我发现这个命令很有用
例如
For git hooks, I found this command useful
For example
git diff --name-only 做同样的事情（可能更直观......）
git diff --name-onlydoes the same (might be more intuitive...)尖角较少的方法：
这似乎与 diff-index 答案做同样的事情，但有一个优点：它会在必要时重建索引，消除 diff-index 的一些不稳定。此外，当存储库通过明显构建临时索引不可写时，
diff可以正常工作（而diff-index，如果索引过时，会说所有内容都已修改，并且无法更新索引来解决这个问题）。An approach with fewer sharp corners:
This appears to do the same thing as the
diff-indexanswer, but with an advantage: it rebuilds the index if necessary, eliminating some flakiness ofdiff-index. Additionally,diffworks correctly when the repository isn't writable by apparently building a temporary index (whilediff-index, if the index is stale, will say everything is modified, and the index can't be updated to fix that).
