创建分支

git branch [name]
git branch dev #创建dev分支
git branch #查看分支

[root@cool360 u02]# git branch
* dev
master

切换分支:

git checkout dev #切换到dev分支
git checkout -d dev ##创建并切换到dev
 git checkout -- readme.txt 回退更改内容在提交之前
[root@oldboy u02]# cat  readme.txt 
1 hehe
2 woshi
3 hehehheheh
[root@oldboy u02]# cat readme.txt 
1 hehe
2 woshi
3 hehehheheh
4 youare
[root@oldboy u02]# git checkout -- readme.txt
[root@oldboy u02]# cat  readme.txt 
1 hehe
2 woshi
3 hehehheheh

合并分支到master:

git checkout dev
echo "this is dev" >dev.txt
git add  dev.txt
git commit -m "add dev.txt"
git checkout master 
git merge dev
[root@oldboy u02]# git merge dev
更新 3eb47f8..ac81cbc
Fast-forward
 dev.txt | 2 ++
 1 file changed, 2 insertions(+)
 create mode 100644 dev.txt

删除分支：

git branch -d dev 

查看分支：

 git branch -a
* master
  remotes/origin/master

冲突解决：

新建分支：
git checkout -b  te
M	dev.txt
切换到一个新分支 'te'
echo "1.branch te" > readme.txt
git add readme.txt 
git commit -m "add te"
git checkout master
echo "2.test" >> readme.txt
git add readme.txt
git commit -m "master change"
然后发生冲突：
[root@oldboy u02]# git commit -m "master change"
[master 99a04b3] master change
 1 file changed, 1 insertion(+)
[root@oldboy u02]# git merge te 
自动合并 dev.txt
冲突（内容）：合并冲突于 dev.txt
自动合并失败，修正冲突然后提交修正的结果。

[root@oldboy u02]# cat  dev.txt 
<<<<<<< HEAD this is 111 ======= this is dev >>>>>>> te

发生冲突只能手动去改成一致的内容才能合并分支。
[root@oldboy u02]# cat dev.txt 
this is dev
再次合并分支
[root@oldboy u02]# git add dev.txt
[root@oldboy u02]# git commit -m  "test111"
[master ff7ee0c] test111
[root@oldboy u02]# git merge te
Already up-to-date.

把分支推送到远端

git push origin  dev
[root@oldboy u02]# git push origin  te

 * [new branch]      dev -> dev
 切换分支发生冲突会导致无法切换对应分支，可使用-f强制切换
git checkout -f master
切换到分支 'master'

删除远程分支：

[root@oldboy u02]# git push origin --delete dev
To git@github.com:Getingjin/demo.git
 - [deleted]         dev

关于分支管理总结：

git branch  -r #列出远端所有分支
git branch -a #列出所有分支包含远端和本地
git branch [branch-name]  //创建新分支
git checkout –b [branch-name] //创建新分支，并且切换到该分支
git branch  --track [branch] [remote-branch]   //创建新分支，与指定的远程分支建立追踪关系
git checkout [branch-name]      //切换至指定分支
git branch –set-upstream [branch] [remote-branch] //本地分支与远程分支建立追踪关系
git merge [branch] //合并指定分支到当前分支
git cherry-pick [commit] //选择一个commit，合并至当前分支
git branch –d [branch-name]  //删除本地分支
git push origin --delete [branch-name]  //删除远程分支
git branch –dr [remote/branch]   //删除远程分支

git-标签管理

git tag v1.0 打标签
git tag  列出标签
git tag -d <tagname> 删除标签
git push origin v1.0 推送标签到远端
[root@oldboy u02]# git push origin v1.0 
Counting objects: 22, done.
Compressing objects: 100% (10/10), done.
Writing objects: 100% (14/14), 1.25 KiB | 0 bytes/s, done.
Total 14 (delta 5), reused 0 (delta 0)
remote: Resolving deltas: 100% (5/5), completed with 1 local object.
To git@github.com:Getingjin/demo.git
 * [new tag]         v1.0 -> v1.0
 git push origin --delete tag <tagname> //删除一个远程标签
[root@oldboy u02]# git push origin --delete  tag v1.0 
To git@github.com:Getingjin/demo.git
 - [deleted]         v1.0
创建本地标签
创建带有说明的标签,-a指定标签名字，-m指定说明文字
git tag -a v1.0.0 -m "version 1.0.0 release"

标签管理小结：

命令git tag –a <tagname> -m "message" //在当前commit状态新建一个tag
命令git tag -l <tagname>   //列出相对应版本号tag
命令git push origin <tagname>      //推送一个本地标签
命令git push origin --tags //推送全部未推送过的本地标签
命令git tag -d <tagname>   //删除一个本地标签
命令git push origin --delete tag <tagname> //删除一个远程标签
命令git push origin :refs/tags/<tagname>   //删除一个远程标签
