Git-查看远程分支、本地分支、创建分支

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.
  remotes/origin/master

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 |     +
  files changed,  insertions(+),  deletions(-)

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

xp.chen@YC-JG-YXKF-PC27 MINGW64 /f/ob ((c8303a9...))
$ git reset --hard 8d8e5ccf24cf6836ab780aa3860270c3876e825a
HEAD is now at 8d8e5cc add battery settigns ui

xp.chen@YC-JG-YXKF-PC27 MINGW64 /f/ob ((8d8e5cc...))
$ git log
commit 8d8e5ccf24cf6836ab780aa3860270c3876e825a (HEAD)
Author: xp.chen <xp.chen@yuneec.com>

    add battery settigns ui

    Change-Id: Ia907ee4e84f54c00a186d31378a7925a6adaba0e

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 '
> .aaaaa
> .bbbb
> '
[master b25154b] .aaaaa .bbbb
  file changed,  insertions(+),  deletions(-)
 create mode  ss.txt

通过git commit --amend 命令可以查看到刚刚的log信息为

.aaaaa
.bbbb
