How to see the changes in a Git commit?
提问by laktak
When I do git diff COMMITI see the changes between that commit and HEAD (as far as I know), but I would like to see the changes that were made by that single commit.
当我这样做时，git diff COMMIT我会看到该提交和 HEAD 之间的更改（据我所知），但我想查看该单个提交所做的更改。
I haven't found any obvious options on diff/ logthat will give me that output.
我没有在diff/上找到任何明显的选项log可以给我那个输出。

To see the diff for a particular COMMIThash:
要查看特定COMMIT哈希的差异 ：
git diff COMMIT~ COMMITwill show you the difference between that COMMIT's ancestor and the COMMIT. See the man pages for git difffor details about the command and gitrevisionsabout the ~notation and its friends.
git diff COMMIT~ COMMIT将向您展示 thatCOMMIT的祖先和COMMIT. 请参阅git diff的手册页以获取有关该命令的详细信息以及有关该符号及其朋友的gitrevisions~。
Alternatively, git show COMMITwill do something very similar. (The commit's data, including its diff - but not for merge commits.) See the git show manpage.
或者，git show COMMIT会做一些非常相似的事情。（提交的数据，包括其差异 - 但不适用于合并提交。）请参阅git show 手册页。

As mentioned in "Shorthand for diff of git commit with its parent?", you can also use git diffwith:
如“ git commit 与其父项的差异的简写？”中所述，您还可以使用git diff：
git diff COMMIT^!
or
或者
git diff-tree -p COMMIT
With git show, you would need (in order to focus on diff alone) to do:
使用 git show，您需要（为了只关注 diff）执行以下操作：
git show --color --pretty=format:%b $COMMIT
The COMMITparameter is a commit-ish:
该COMMIT参数是一个commit-ish：
A commit objector an objectthat can be recursively dereferenced to a commit object. The following are all commit-ishes: a commit object, a tag objectthat points to a commit object, a tag object that points to a tag object that points to a commit object, etc.
甲commit对象或一个对象可以被递归地解除引用到一个提交对象。以下是所有提交-ishes：提交对象，标签对象是指向一个commit对象，标签对象指向一个标签对象指向一个commit对象，等等。
See gitrevision "SPECIFYING REVISIONS"to reference a commit-ish.
See also "What does tree-ish mean in Git?".
请参阅gitrevision "SPECIFYING REVISIONS"以引用 commit-ish。
另请参阅“ Git 中的 tree-ish 是什么意思？”。

You can also try this easy way:
你也可以试试这个简单的方法：
git show <COMMIT>
回答by Adam Salma
git showshows the changes made in the most recent commit.
git show显示在最近一次提交中所做的更改。
Equivalent to git show HEAD.
相当于git show HEAD。
git show HEAD~1takes you back 1 commit.
git show HEAD~1带你回 1 次提交。
回答by Alex
I usually do:
我通常这样做：
git diff HEAD~1
To show the changes regarding the last commit. If you have more commits just increase the number 1 to how many commits diff you want to see.
显示有关上次提交的更改。如果您有更多提交，只需将数字 1 增加到您想要查看的提交差异数量。

First get the commit ID using,
首先使用提交 ID，
git log #to list all
Or
或者
git log -p -1 #last one commit id
Copy commit id.
复制提交 ID。
Now we use two methods to list changes from a specific commit,
现在我们使用两种方法来列出来自特定提交的更改，
Method 1:
方法一：
git diff commit_id^! #commit id something like this 1c6a6000asad012
git diff commit_id^! #commit id something like this 1c6a6000asad012
Method 2:
方法二：
git show commit_id
For example: git show 1c6a600a

git show <commit_sha>
This will show you just what's in that commit. I think you can do a range it by just putting a space between two commit shas.
这将向您展示该提交中的内容。我认为您可以通过在两个提交 shas 之间放置一个空格来实现它的范围。
git show <beginning_sha> <ending_sha>
which is pretty helpful if you're rebasing often because your feature logs will all be in a row.
如果您经常进行变基，这非常有用，因为您的功能日志将全部排成一行。

From the man page for git-diff(1):
从git-diff(1)的手册页：
git diff [options] [<commit>] [--] [<path>…]
git diff [options] --cached [<commit>] [--] [<path>…]
git diff [options] <commit> <commit> [--] [<path>…]
git diff [options] <blob> <blob>
git diff [options] [--no-index] [--] <path> <path>
Use the 3rd one in the middle:
使用中间的第三个：
git diff [options] <parent-commit> <commit>
Also from the same man page, at the bottom, in the Examples section:
同样来自同一手册页的底部，在示例部分：
$ git diff HEAD^ HEAD <3>
Compare the version before the last commit and the last commit.
比较上次提交和上次提交之前的版本。
Admittedly it's worded a little confusingly, it would be less confusing as
诚然，它的措辞有点令人困惑，因为它不会那么令人困惑
Compare the most recent commit with the commit before it.
将最近的提交与其之前的提交进行比较。

The following seems to do the job; I use it to show what has been brought in by a merge.
以下似乎可以完成这项工作；我用它来显示合并带来了什么。
git whatchanged -m -n 1 -p <SHA-1 hash of merge commit>
回答by John_West
Another possibility:
另一种可能：
git log -p COMMIT -1
