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.py                       | 19 +++++++++++++++++++
 myfolder/file.js                       |  7 +++++++
 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

我在windows 10上运行的是Git 2.6.1.windows.1版本，所以我需要对Nevik的答案稍作修改（用波浪号代替插入符号）：

git diff COMMIT~ COMMIT

另一个选项是引用插入符号：

git diff "COMMIT^" COMMIT

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）

您也可以尝试以下简单方法：

git show <COMMIT>

您可以使用git diff HEAD HEAD ^1查看与父提交的差异。

如果您只想查看文件列表，请添加--stat选项。

如“gitcommit与其父级的差异的速记？”中所述，您也可以将gitdiff用于：

git diff COMMIT^!

or

git diff-tree -p COMMIT

使用gitshow，您需要（为了只关注diff）：

git show --color --pretty=format:%b COMMIT

COMMIT参数是COMMIT-ish：

提交对象或可以递归地取消引用到提交对象的对象。以下是所有提交对象：提交对象、指向提交对象的标记对象、指向指向提交对象标记对象的标签对象等。

参见gitrevision“指定修订”以引用提交。另请参阅“tree-ish在Git中是什么意思？”。
