Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show, and restored (potentially on top of a different commit) with git stash apply. Calling git stash without any arguments is equivalent to git stash save. A stash is by default listed as "WIP on branchname …", but you can give a more descriptive message on the command line when you create one.

The latest stash you created is stored in refs/stash; older stashes are found in the reflog of this reference and can be named using the usual reflog syntax (e.g. stash@{0} is the most recently created stash, stash@{1} is the one before it,stash@{2.hours.ago} is also possible).

git stash list

查看之前缓存的所有stash

$ git stash list
stash@{0}: WIP on temp: 36b0f5f 删除HSDataFrameManager类中多余的代码      //第二次的stash，覆盖了第一次【git stash apply的时候，只能出现这一次的，上一次的不会出现】
stash@{1}: WIP on temp: 36b0f5f 删除HSDataFrameManager类中多余的代码      //第一次的stash
stash@{2}: WIP on temp: c723e17 接收到消息的时候，打印出消息类型，如果消息内部有
stash@{3}: WIP on temp: 18fa2a3 连接通讯模块时，需要将主窗体的窗口句柄传递给通讯

temp是分支的名字

第0个和第1个虽然看起来完全一样，但实际上是不同的

git stash show

查看list中的某一次stash

$ git stash show stash@{0}
ZBMYun/SourceCode/ZITakerHS/ZITaker/SystemConfig.ini | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)

$ git stash show stash@{1}
ZBMYun/SourceCode/ZITakerHS/ZITaker/UI/Main.cs | 2 +-
ZBMYun/SourceCode/ZITakerHS/ZITaker/ZbmStorage_Component.ini | 2 +-
2 files changed, 2 insertions(+), 2 deletions(-)

git stash show stash@{0} -u

添加-u参数可以输出某一次stash的所有文件差异对比

git stash apply

可以apply指定的stash，如果你不指定的话，默认apply最近一次的stash

If you want to apply one of the older stashes, you can specify it by naming it, like this: git stash apply stash@{2}.

If you don’t specify a stash, Git assumes the most recent stash and tries to apply it:

git stash drop

$ git stash list
stash@{0}: WIP on local: 63b9f1b DebugInfoManager类，在FormMain加载的时候需要主
stash@{1}: WIP on svn: 78ab728 设备第一次上线后，直接发送采集数据，在这种情况下

$ git stash drop stash@{0}
Dropped stash@{0} (1136bc142780259d8541c7e3a605ff2250cc9427)

pop [--index] [-q|--quiet] [<stash>]

Remove a single stashed state from the stash list and apply it on top of the current working tree state, i.e., do the inverse operation of git stash save. The working directory must match the index.

Options:

save [-p|--patch] [-k|--[no-]keep-index] [-u|--include-untracked] [-a|--all] [-q|--quiet] [<message>]

Save your local modifications to a new stash, and run git reset --hard to revert them.

The <message> part is optional and gives the description along with the stashed state.

For quickly making a snapshot, you can omit both "save" and <message>, but giving only <message> does not trigger this action to prevent a misspelled subcommand from making an unwanted stash.
