如果您只想查看最新提交中的更改，只需gitshow即可。

一些答案漏掉了一个特例。如何查看根提交所做的更改，因为它没有父/祖先。

Both

git diff＜root_commit＞^<root_commit>

and

git diff＜root_commit＞~<root_commit>

抛出错误。

$git diff 27e521ca73a46b2d3a28568dc49fced81e46aaea~ 27e521ca73a46b2d3a28568dc49fced81e46aaea
fatal: ambiguous argument '27e521ca73a46b2d3a28568dc49fced81e46aaea~': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

git diff＜root_commit＞^！

显示diff btw根提交和HEAD。像这样：

$ git diff 27e521ca73a46b2d3a28568dc49fced81e46aaea^!

（这些是所有提交对我的根提交和HEAD所做的更改）。

对于根提交

我只发现

git show--color--prett=格式：%b<root_commit_hash>

作品

像这样：

$ git show --color --pretty=format:%b 27e521ca73a46b2d3a28568dc49fced81e46aaea

（我的根提交仅添加了README）

检查文件更改的更简单方法（示例）

# 1. Checkout a branch and see the list of commits
git log --oneline -5

# > Output
9b9b1f8 (HEAD -> master) Updated ABC
d58e5da chore: Added files
5a4aa2c chore: Added my pipeline
bb2b0b7 feat: Added ABC
473f711 feat: Added ZYX

# 2. Pick a commit hash and check which files were modified
git show --stat --oneline d58e5da

# > Output
d58e5da chore: Added versioning files
 Someabcfile                            | 18 ++++++++++++++++++

 myfolder/file.txt                      |  1 +
 4 files changed, 45 insertions(+)

# 3. Pick a file to check the differences
git show d58e5da myfolder12/file.py

或者，从列表中检查一次提交中的所有文件差异：

git show d58e5da

您可以在git的特定地址上单击每次提交以查看如果您使用工具提交，您可以通过展会历史记录

要通过提交查看作者和时间，请使用gitshowCOMMIT。这将导致如下情况：

commit 13414df70354678b1b9304ebe4b6d204810f867e
Merge: a2a2894 3a1ba8f
Author: You <you@you.com>
Date:   Fri Jul 24 17:46:42 2015 -0700

     Merge remote-tracking branch 'origin/your-feature'

如果您想查看哪些文件已更改，请使用上面“合并”行中的值运行以下命令：git diff--stat a2a2894 3a1ba8f。

如果要查看实际差异，请运行git-stat a2a2894 3a1ba8f。

如果您只想查看最新提交中的更改，只需gitshow即可。
