git stash 用法
git stash用于将当前工作区的修改暂存起来,就像堆栈一样,可以随时将某一次缓存的修改再重新应用到当前工作区。

注意,git stash pop 弹出成功后,暂存列表里面就没有了,如果当前工作区不干净,弹出时有冲突,则暂存列表会继续保留修改。

发现stash@{0}对应func2的修改, stash@{1}对应func1的修改,原来新入栈的修改,其代号为0,循环命名。
yang@Ubuntu64:~/code/linux/git$ git stash apply stash@{}
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)

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

+void func1(void) {printf("this is func1");}

可见git stash apply可以将列表中任何一次修改应用到当前工作区,我们再次git stash list一把:
yang@Ubuntu64:~/code/linux/git$ git stash list
stash@{}: WIP on master: 452b08d rename hello as hello.c
stash@{}: WIP on master: 452b08d rename hello as hello.c
yang@Ubuntu64:~/code/linux/git$ vim hello.c
yang@Ubuntu64:~/code/linux/git$ git diff
diff --git a/hello.c b/hello.c
index e69de29..786c214
--- a/hello.c
+++ b/hello.c
@@ -, +, @@
+void func3(void) {printf("this is func3");}
+void main(void) {return func3();}
yang@Ubuntu64:~/code/linux/git$ git stash save "this is func3"
Saved working directory and index state On master: this is func3
HEAD is now at 452b08d rename hello as hello.c
yang@Ubuntu64:~/code/linux/git$ git stash list
stash@{}: On master: this is func3
stash@{}: WIP on master: 452b08d rename hello as hello.c
stash@{}: WIP on master: 452b08d rename hello as hello.c
我们在save后面指定一个字符串,作为提醒,这样在git stash list查看时就能知道每一个代号对应的修改了。
