git分支管理命令
查看分支： git branch
创建分支： git branch <name>
切换分支： git checkout <name>
创建+切换分支 git checkout -b <name>
合并某个分支到当前分支：git merge <name>
删除分支: git branch -d <name>
创建dev分支
然后切换到dev分支
$git checkout -b dev
git checkout 命令加上 -b 参数表示创建并切换
相当于：
$ git branch dev
$ git checkout dev
查看分支
ssgao@ssgao-PC MINGW64 ~/git/hzzhgl (dev)
$ git branch
* dev
master
git branch命令会列出所有分支，当前分支前面会标一个*号。
查看远程分支
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
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/kafka_changed
remotes/origin/master
remotes/origin/v1.0
remotes/origin/v1.1
remotes/origin/v1.2.0_dubbo_refactor_from_adcm
合并分支
git merge 命令用于合并指定分支到当前分支
将dev分支合并到master分支
$ git merge dev
Updating d17efd8..fec145a
Fast-forward
readme.txt | 1 +
1 file changed, 1 insertion(+)
删除分支
git branch -d <name>
如果要丢弃一个没有被合并过的分支，可以通过git branch -D <name>强行删除。
分支合并时的冲突解决
准备新的dev 分支，继续我们的开发
$git checkout -b dev
switch to a new branch 'dev'
在分支dev上添加修改文件readme.txt ，并在dev上进行提交
$ git add readme.txt
$ git commit -m "AND simple"
[feature1 75a857c] AND simple
1 file changed, 1 insertion(+), 1 deletion(-)
切换到master分支
$ git checkout master
Switched to branch 'master'
Your branch is ahead of 'origin/master' by 1 commit.
-- git 还可以自动提示我们，当前master分支比远程的master分支要超前提交一个分支--
在master分支修改readme.txt，并在mater上进行提交
$ git add readme.txt
$ git commit -m "& simple"
[master 400b400] & simple
1 file changed, 1 insertion(+), 1 deletion(-)
这是将dev分支合并到master分支
$ git merge dev
Auto-merging readme.txt
CONFLICT (content): Merge conflict in readme.txt
Automatic merge failed; fix conflicts and then commit the result.
这时就发生了冲突,git会提示我们文件readme.txt发生了冲突,必须要我们手动解决后在提交
$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 2 commits.
# Unmerged paths:
# (use "git add/rm <file>..." as appropriate to mark resolution)
# both modified: readme.txt
no changes added to commit (use "git add" and/or "git commit -a")
使用vi编辑器打开该冲突文件

Creating a new branch is quick & simple.

Creating a new branch is quick AND simple.
>>>>>>> feature1
Git用<<<<<<<，=======，>>>>>>>标记出不同分支的内容，我们修改如下后保存：
Creating a new branch is quick & simple.
手动修改冲突后，重新加入到缓存区
$ git add readme.txt
$ git commit -m "conflict fixed"
[master 59bc1cb] conflict fixed
查看分支合并情况
$ git log --graph --pretty=oneline --abbrev-commit
* 59bc1cb conflict fixed

* | 400b400 & simple
