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

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。

我喜欢下面的命令来比较特定的提交和上次提交：

git diff <commit-hash>^-

例子：

git diff cd1b3f485^-

检查完整更改：

  git diff <commit_Id_1> <commit_Id_2>

仅检查更改/添加/删除的文件：

  git diff <commit_Id_1> <commit_Id_2> --name-only

注意：对于检查diff而不在两者之间进行提交，您不需要输入提交id。

还可以查看特定文件的两次提交之间的更改。

git diff <commit_Id_1> <commit_Id_2> some_dir/file.txt

要查看特定COMMIT哈希的差异，其中COMMIT是提交的哈希：

gitdiffCOMMIT~COMMIT将向您展示COMMIT的祖先和COMMIT之间的区别。有关命令和gitrevisions的详细信息，请参阅gitdiff的手册页。

或者，gitshowCOMMIT也会做类似的事情。（提交的数据，包括其diff，但不包括合并提交的数据。）请参阅gitshow手册页。

（gitdiffCOMMIT也会显示COMMIT和头部之间的区别。）
