如何获取git存储库中特定文件的更改历史记录

Question

我想做的事情如下:

git history my_file

可能的输出

2010-05-16
+ add this line
+ more code here

2010-05-15
+ delete code below
- bad code
- more bad codd

2010-05-12
+ changes made here

Answer 1

尝试:

git log -p -- filename

Answer 2

最接近你想要的是,来自git log:

git log -p -U0 --pretty=format:%ai -- filename

• -p:正如Charles Bailey在他的回答中提到的那样:生成补丁
• -U0:使用0行上下文而不是通常的三行生成差异.
• --pretty=format:%ai:在补丁输出前面加上作者日期,ISO 8601格式.

例:

/c/Prog/Git/git2/git (master)
$ git log -p -U0 --pretty=format:%ai -- wt-status.c
