Git的有些命令已经融入到血液中，通常情况下大脑可能还没有想出来，键盘却已经敲出来了。 但是同样有一些Git命令，平时用不上，但真正遇到了使用场景时，却怎么也想不起来，不得不面向CSDN编程。 比如有时候git commit 的提交说明手残打错了， 想要回撤总也想不起来怎么搞。在多次踩坑之后，我特意整理了这几个命令，可能几个月也用不上，记忆成本也不到，但是如果不知道，有时还挺恼火~ ~ 诸君共勉。

批量删除远程分支

git branch -a | grep remote | grep ogenes | awk -F '/' '{print $3"/"$4"/"$5}' | xargs git push origin --delete

修改最近一次 git commit 内容

git commit --amend

取消最近一次提交，并保留文件更改

git reset --mixed head~1

更新远程分支

git remote update origin --prune

➜  ogenes-permission git:(main) git remote update origin --prune
Fetching origin
From github.com:ogenes/ogenes-permission
 - [deleted]         (none)     -> origin/pro

远程仓库改名

git remote rename origin ogenes

多个仓库地址

1. 查看远程仓库

   ➜  docker-lnmp git:(main) git remote -v
   ogenes  git@github.com:ogenes/docker-lnmp.git (fetch)
   ogenes  git@github.com:ogenes/docker-lnmp.git (push)
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (fetch)
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (push)
   

2. 删除一个远程仓库

   ➜  docker-lnmp git:(main) git remote rm ogenes
   ➜  docker-lnmp git:(main) git remote -v
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (fetch)
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (push)
   

3. 新增一个远程仓库

   ➜  docker-lnmp git:(main) git remote add ogenes git@github.com:ogenes/docker-lnmp.git
   ➜  docker-lnmp git:(main) git remote -v 
   ogenes  git@github.com:ogenes/docker-lnmp.git (fetch)
   ogenes  git@github.com:ogenes/docker-lnmp.git (push)
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (fetch)
   origin  git@gitlab.ogenes.cn:john.yi/docker-lnmp.git (push)
   

4. 修改远程仓库地址

   ➜  docker-lnmp git:(main) git remote set-url origin git@gitlab.ogenes.cn/docker-lnmp.git 
   ➜  docker-lnmp git:(main) git remote -v
   ogenes  git@github.com:ogenes/docker-lnmp.git (fetch)
   ogenes  git@github.com:ogenes/docker-lnmp.git (push)
   origin  git@gitlab.ogenes.cn/docker-lnmp.git (fetch)
   origin  git@gitlab.ogenes.cn/docker-lnmp.git (push)
   

5. 推送到指定仓库

   ➜  docker-lnmp git:(feature/ogenes) git push ogenes feature/ogenes
   Enumerating objects: 9, done.
   Counting objects: 100% (9/9), done.
   Delta compression using up to 8 threads

   Writing objects: 100% (6/6), 603 bytes | 603.00 KiB/s, done.

   remote: 
   remote: Create a pull request for 'feature/ogenes' on GitHub by visiting:
   remote:      https://github.com/ogenes/docker-lnmp/pull/new/feature/ogenes
   remote: 
   To github.com:ogenes/docker-lnmp.git
    * [new branch]      feature/ogenes -> feature/ogenes
   
   

6. 从指定仓库拉取

➜  docker-lnmp git:(main) git pull ogenes
From github.com:ogenes/docker-lnmp
 * [new branch]      main       -> ogenes/main
You asked to pull from the remote 'ogenes', but did not specify
a branch. Because this is not the default configured remote
for your current branch, you must specify a branch on the command line.
