Git自学成才——git stash

如果有未提交的更改，是不能git pull的，下面演示一下如何不提交更改，拉取代码，实现Android Studio的Update project

修改一个文件

D:\client>git status
On branch lichen_test
Your branch is up-to-date with 'origin/lichen_test'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   xxx.java

no changes added to commit (use "git add" and/or "git commit -a")

说明有一个文件被修改了，还没有add，相当于本地修改。这时，我想拉取服务端最新代码，发现是error的：

D:\client>git pull --rebase
error: Cannot pull with rebase: You have unstaged changes.

因为git pull只是在本地更改commit之后，才是被允许的。

先看一下之前已经stash过的记录：

D:\client>git stash list
stash@{0}: On lichen_test: Uncommitted changes before Update at 2016/5/17 11:22

然后把刚才的本地修改藏起来stash：

D:\client>git stash
Saved working directory and index state WIP on lichen_test: 6acf645 something
HEAD is now at 6acf645 something                                                                                                                   

之后，看一下状态：

D:\client>git status
On branch lichen_test
Your branch is up-to-date with 'origin/lichen_test'.
nothing to commit, working directory clean

D:\client>git stash list
stash@{0}: WIP on lichen_test: 6acf645 something                                                                              

看到的状态是没有需要commit的，工作空间是干净的；stash的历史记录里又多了一条。

然后执行git pull就可以了：

D:\client>git pull --rebase
Current branch lichen_test is up to date.

刚才藏起来的更改恢复回来：

D:\client>git stash pop
On branch lichen_test
Your branch is up-to-date with 'origin/lichen_test'.
Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   xxx.java

no changes added to commit (use "git add" and/or "git commit -a")
Dropped refs/stash@{0} (c09db35f5eb59ada6770fe6ab6073b4f00bc912a)

看一下历史记录

D:\client>git stash list
stash@{0}: On lichen_test: Uncommitted changes before Update at 2016/5/17 11:22

这样就完成了一次Android Studio的Update工程

总结一下stash命令：

git stash #可用来暂存当前正在进行的工作
git stash pop #从Git栈中读取最近一次保存的内容
git stash list #显示Git栈内的所有备份
git stash clear #清空Git栈
git stash apply stash@{1} #可以将你指定版本号为stash@{1}的工作取出来
