git 之分支篇

1 查看远程分支

[plain]
view plain
copy





$ git branch -a
* br-2.1.2.2
master
remotes/origin/HEAD -> origin/master
remotes/origin/br-2.1.2.1
remotes/origin/br-2.1.2.2
remotes/origin/br-2.1.3
remotes/origin/master

2 查看本地分支

[plain]
view plain
copy





shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git branch
* br-2.1.2.2
master

3 创建分支

[plain]
view plain
copy





shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git branch test

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git branch
* br-2.1.2.2
master
test

线面是把分支推到远程分支

[plain]
view plain
copy





$ git push origin test

4 切换分支到test

[plain]
view plain
copy





shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git branch
* br-2.1.2.2
master
test

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git checkout test
M jingwei-server/src/main/java/com/taobao/jingwei/server/service/cmd/GetCustomerTarCmd.java
M jingwei-server/src/main/java/com/taobao/jingwei/server/util/ServerUtil.java
Switched to branch 'test'

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (test)
$ git branch
br-2.1.2.2
master
* test

M 表示cong 原来分支（上一次修改没有提交br-2.1.2.2）带过来的修改
5 删除本地分支 git branch -d xxxxx

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (test)

[plain]
view plain
copy





$ git checkout br-2.1.2.2
M jingwei-server/src/main/java/com/taobao/jingwei/server/service/cmd/GetCustomerTarCmd.java
M jingwei-server/src/main/java/com/taobao/jingwei/server/util/ServerUtil.java
Switched to branch 'br-2.1.2.2'

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git br
* br-2.1.2.2
master
test

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git br -d test
Deleted branch test (was 17d28d9).

shuohailhl@SHUOHAILHL-PC /f/ggg/jingwei (br-2.1.2.2)
$ git br
* br-2.1.2.2
master

6 查看本地和远程分支 -a。前面带*号的代表你当前工作目录所处的分支

[plain]
view plain
copy





remotes/origin/HEAD -> origin/master #啥意思呢？

”在clone完成之后，Git 会自动为你将此远程仓库命名为origin（origin只相当于一个别名，运行git remote –v或者查看.git/config可以看到origin的含义），并下载其中所有的数据，建立一个指向它的master 分支的指针，我们用(远程仓库名)/(分支名) 这样的形式表示远程分支，所以origin/master指向的是一个remote branch（从那个branch我们clone数据到本地）“

这个是执行 git remote -v 的结果，看出来origin其实就是远程的git地址的一个别名。

$ git remote -v
origin git@gitlab.alibaba-inc.com:middleware/jingwei.git (fetch)
origin git@gitlab.alibaba-inc.com:middleware/jingwei.git (push)
