在git中生成特定提交的差异文件 [英] Generate diff file of a specific commit in git

问题描述

当头部处于特定提交状态时，我想获取一个diff文件，以便可以将头部降低到一个更低的级别，然后在有和没有应用diff文件的情况下尝试测试功能.因此，有一种方法可以生成特定提交的差异文件.

When the head is at a particular commit, I want to get a diff file so that I can reduce the head to one more level down and then try the testing functionality with and without applying the diff file. So is there a way to generate a diff file of a specific commit.

即使可以在提交前后更改头，此方法也更方便.

Even though there is a way to change the head before and after commit, this method comes more handy.

推荐答案

查看特定提交的更改.

$ git diff <commit-sha> -p

OR,
$ git show --decorate <commit-sha>    # see 'Author', 'Date' and 'diff'

查看两次提交的区别.

$ git diff <commit1> <commit2>

请参阅file更改以进行特定的提交.

See the file changes for a specific commit.

$ git show <commit>:<file>

查看一段时间内的所有更改(例如1 day).

See all the changes for a time duration (say, 1 day).

$ git whatchanged --since="1 day ago" -p
$ git whatchanged --since="1 day ago" -p <file>   # see changes for a specific file only
