1.查看本地分支
$ git branch
* br-2.1.2.2
master
2.查看远程分支
$ git branch -r
origin/HEAD -> origin/master
origin/feature/IOS_visualtrack
origin/feature/android_visualtrack
origin/master
3.查看所有分支
$ 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
PS: git branch -r 无法获取远程分支，ui可以看见分支但是git 命令无法查看
原因 git branch -a 这条命令并没有每一次都从远程更新仓库信息，我们可以手动更新一下
git fetch origin
git branch -a
4.切换远程分支
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/Release
remotes/origin/master
$ git checkout -b myRelease origin/Release
Branch myRelease set up to track remote branch Release from origin.
Switched to a new branch 'myRelease'
PS: 作用是checkout远程的Release分支，在本地起名为myRelease分支，并切换到本地的myRelase分支
5.合并分支
合并前要先切回要并入的分支
以下表示要把issue1234分支合并入master分支
$: git checkout master
$: git merge issue1234
Merge made by recursive.
README | 1 +

6.撤消上一次commit的内容(该操作会彻底回退到某个版本，本地的源码也会变为上一个版本的内容)
git reset --hard <commit-id>
以下表示要撤消“update build gradle configuration file”这一次的commit id,返回到"add battery settings ui"这一次的commit id,
xp.chen@YC-JG-YXKF-PC27 MINGW64 /f/ob ((c8303a9...))
$ git log

7. git commit -m 注释换行
git commit -m 注释可以通过单引号来换行，比如：
$ git commit -m '
> 1.aaaaa
> 2.bbbb
> '
[master b25154b] 1.aaaaa 2.bbbb
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 ss.txt
通过git commit --amend 命令可以查看到刚刚的log信息为
1.aaaaa
2.bbbb
