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

另一种可能性：

git log -p COMMIT -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>

使用中间的第三个：

git diff [options] <parent-commit> <commit>

同样从同一手册页底部的示例部分：

$ git diff HEAD^ HEAD      <3>

比较上次提交和上次提交之前的版本。

诚然，它的措辞有点混乱，但也不会那么混乱

将最近的提交与之前的提交进行比较。

我通常会：

git diff HEAD~1

显示有关上次提交的更改。如果您有更多的提交，只需将数字1增加到您希望看到的提交差异。

对我来说，这很好

git show COMMIT --compact-summary

显示下一个信息

输出扩展头信息的浓缩摘要，例如diffstat中的文件创建或删除（“new”或“gone”，如果是符号链接，可选“+l”）和模式更改（“+x”或“-x”分别用于添加或删除可执行位）。信息放在文件名部分和图形部分之间。暗示--stat。

此命令将获取Git父提交哈希：

git log -n 2 <commit-hash>

之后，gitdiff工具<commithash><parentcommithash>

例子：

bonnie@bonnie ~/ $ git log -n 2 7f65b9a9d3820525766fcba285b3c678e889fe3

CSS changed to maintain the aspect ratio of the channel logos and to fit them properly.

The ratio of the height to width of the channel images are maintained.

在此之后

git difftool 7f65b9a9d3820525766fcba285b3c678e889fe3b c3a61f17e14e2b80cf64b172a45f1b4826ee291f
