git如何从远程非master分支更新到本地对应分支

自己实例

正确步骤

如果本地有分支，那就删除本地分支

删除本地分支:：git branch -d 2018_4_18_second

切换分支： git checkout master

将远程分支上的东西拉下来： git checkout -b 2018_4_18_second origin/2018_4_18_second

# 列出所有本地分支$ git branch
# 列出所有远程分支$ git branch -r
# 列出所有本地分支和远程分支$ git branch -a
# 新建一个分支，并切换到该分支$ git checkout -b [branch]

拉文件下来的话

git pull https://github.com/fry404006308/m_Orchestrate.git 2018_4_18_second

或者试试

git pull

善于使用帮助命令，特别好用

从帮助命令知道怎么弄，超级快

git help pull

然后你会看到这样的示例用法：

 EXAMPLES

 Update the remote-tracking branches for the repository you cloned from, then merge one of them into your current branch:

 $ git pull

 $ git pull origin

 Normally the branch merged in is the HEAD of the remote repository, but the choice is determined by the branch.<name>.remote and branch.<name>.merge options; see git-config() for details.

 Merge into the current branch the remote branch next:

 $ git pull origin next

 This leaves a copy of next temporarily in FETCH_HEAD, but does not update any remote-tracking branches. Using remote-tracking branches, the same can be done by invoking fetch and merge:

 $ git fetch origin

 $ git merge origin/next

 If you tried a pull which resulted in complex conflicts and would want to start over, you can recover with git reset.

所以就知道怎么弄了

将远程git仓库里的指定分支拉取到本地（本地不存在的分支）

当我想从远程仓库里拉取一条本地不存在的分支时：

git checkout -b 本地分支名 origin/远程分支名

这个将会自动创建一个新的本地分支，并与指定的远程分支关联起来。

例如远程仓库里有个分支dev2,我本地没有该分支，我要把dev2拉到我本地：

若成功，将会在本地创建新分支dev2,并自动切到dev2上。

如果出现提示：

fatal: Cannot update paths and switch to branch 'dev2' at the same time.

Did you intend to checkout 'origin/dev2' which can not be resolved as commit?

表示拉取不成功。我们需要先执行

git fetch

然后再执行

git checkout -b 本地分支名 origin/远程分支名

即可。

git checkout -b 2018_4_18_second

忘记 pull up了远程建立分支后，要pull up更新一下本地，就可以显示出来了，新手，弄了几个小时，才弄出来。。

git pull之后，才显示远程分支

别人实例

git一般有很多分支，我们clone到本地的时候一般都是master分支，那么如何切换到其他分支呢？主要命令如下：

1. 查看远程分支

$ git branch -a
我在mxnet根目录下运行以上命令：

~/mxnet$ git branch -a

* master

  remotes/origin/HEAD -> origin/master

  remotes/origin/master

  remotes/origin/nnvm

  remotes/origin/piiswrong-patch-1

  remotes/origin/v0.9rc1

可以看到，我们现在在master分支下

2. 查看本地分支

~/mxnet$ git branch

* master

3. 切换分支

$ git checkout -b v0.9rc1 origin/v0.9rc1

Branch v0.9rc1 set up to track remote branch v0.9rc1 from origin.

Switched to a new branch 'v0.9rc1'

＃已经切换到v0.9rc1分支了

$ git branch

  master

* v0.9rc1

＃切换回master分支

$ git checkout master

Switched to branch 'master'

Your branch is up-to-date with 'origin/master'.
