Git基础操作：合并某个分支的一个commit到另一个分支

有的时候不小心在错误的分支A上开发了一点代码，也已经提交了，这个时候如果想把这部分代码移到正确的分支B上可以如下操作

1. 使用git log命令找到错误提交的那次commitid

git log
commit 8b19200eed045d5bef5b304c30eb76d74f3943ea (HEAD -> A, origin/A)
Author: alioo <xxx@yyy.com>
Date:   2021-03-08T21:45:40+08:00

    取消没有必要的RecommendException

1. checkout到分支B之后，使用cherry-pick命令进行merge

git checkout B
Switched to branch 'B'
Your branch is up to date with 'origin/B'.

 git cherry-pick 8b19200eed045d5bef5b304c30eb76d74f3943ea
[A b2da47b48] 取消没有必要的RecommendException
