Git常用操作

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

复制代码
$ 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
  复制代码
  4.切换远程分支

复制代码
$ 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’
复制代码
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 +
1 files changed, 1 insertions(+), 0 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

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,

复制代码
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：

复制代码
$ 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
复制代码
通过git commit --amend 命令可以查看到刚刚的log信息为

1.aaaaa
2.bbbb
