git生成patch文件

一、通过git diff 命令生成patch文件
1.还未提交的修改

?

1	git diff > commit.patch

2.已提交的修改

?

1	git diff 3da71ca35 8b5100cdcd > commit.patch

注）3da71ca35 在8b5100cdcd 前面
3.已经add但是未commit的修改

?

1	git diff --cached > commit.patch

4.检查patch是否可以应用

?

1	git apply --check commit.patch

5.打补丁

?

1	git apply commit.patch
