Git 管理に追加されていないファイルは

`stash` しても `stash` 領域に待避されません:

|

|

```console
|
|

|

$ git status
|
|

|
+
On branch master
|
|

|

Untracked files:

|

(use "git add <file>..." to include in what will be committed)

test.txt

```
|
|

|

|
|

|

Git 管理に追加すると `stash` は成功します:
|
|
31
|
+
|
|
32
|
+
```console
|
|
33
|
+
$ git add test.txt
|
|
34
|
+
|
|
35
|
+
$ git stash
|
|
36
|
+
Saved working directory and index state WIP on master: 68829db First commit
|
|
37
|
+
|
|
38
|
+
$ git status
|
|
39
|
+
On branch master
|
|
40
|
+
nothing to commit, working tree clean
|
|
41
|
+
|
|
42
|
+
$ git stash list
|
|
43
|
+
stash@{0}: WIP on master: 68829db First commit
|
|
44
|
+
|
|
45
|
+
$ git stash show 0
|
|
46
|
+
test.txt | 1 +
|
|
47
|
+
1 file changed, 1 insertion(+)
|
|
48
|
+
```
|
|
49
|
+
|
|
50
|
+
この場合は `checkout` してもファイルはワーキングツリーではなく
|
|
51
|
+
`stash` 領域に存在します:
|
|
52
|
+
|
|
53
|
+
```console
|
|
54
|
+
$ git checkout -b feature
|
|
55
|
+
Switched to a new branch 'feature'
|
|
56
|
+
|
|
57
|
+
$ git status
|
|
58
|
+
On branch feature
|
|
59
|
+
nothing to commit, working tree clean
|
|
60
|
+
|
|
61
|
+
$ git stash list
|
|
62
|
+
stash@{0}: WIP on master: 68829db First commit
|
|
63
|
+
|
|
64
|
+
$ git stash show 0
|
|
65
|
+
test.txt | 1 +
|
|
66
|
+
1 file changed, 1 insertion(+)
|
|
67
|
+
```
|
|
68
|
+
|
|
69
|
+
もし、Git 管理されていないファイルがワーキングツリーにある状態で `checkout` が成功すると、
|
|
70
|
+
ファイルはワーキングツリーに残ったままになります:
|
|
71
|
+
|
|
72
|
+
```console
|
|
73

|
|
77
|

|
|
78
|
+
|
|
79
|
+
nothing added to commit but untracked files present (use "git add" to track)
|
|

|

|
|
81
|

|

|

$ git status

|
|
86
|
+
Untracked files:
|
|
87
|
+
(use "git add <file>..." to include in what will be committed)
|
|
88
|
+
test.txt
|
|
89
|
+
|
|
90
|
+
nothing added to commit but untracked files present (use "git add" to track)
|
|

```
