```

### apply patch

patch -d jasper-1.900.1 -p1 < jasper-patch/jasper-1.900.1.patch
```


## jasper-1.900.2

### create patch

## patch 解释
选项 -d <目录>：指定工作目录

选项 -p <层级>：去掉多少级目录

### 示例一：
patch 文件格式：

diff -Nrua jasper-1.900.1/jasper.spec new/jasper-1.900.1/jasper.spec

patch 命令：

patch -d jasper-1.900.1 -p1 < jasper-patch/jasper-1.900.1.patch

解释：

-d jasper-1.900.1 ：当作工作目录

-p 1 ：去掉1层目录，即变成下面样子：

diff -Nrua jasper.spec jasper-1.900.1/jasper.spec

在 jasper-1.900.1 目录下，能找到 jasper.spec，所以不会报错


### 示例二：
patch 文件格式：

diff -Nrua ./jasper-1.900.1/jasper.spec ./new/jasper-1.900.1/jasper.spec

patch 命令：

patch -d jasper-1.900.1 -p2 < jasper-patch/jasper-1.900.1.patch

解释：

-d jasper-1.900.1 ：当作工作目录

-p 2 ：去掉2层目录，即变成下面样子：

diff -Nrua jasper.spec jasper-1.900.1/jasper.spec

在 jasper-1.900.1 目录下，能找到 jasper.spec，所以不会报错

若 patch 命令改为 patch -d jasper-1.900.1 -p1 < jasper-patch/jasper-1.900.1.patch，

去掉一层目录会变成这样：diff -Nrua jasper-1.900.1/jasper.spec new/jasper-1.900.1/jasper.spec，

所以在 jasper-1.900.1 目录下，不能找到 jasper-1.900.1/jasper.spec，所以报错；

解决办法有2种：

1. 再去掉一层目录，

变成这样：diff -Nrua jasper.spec jasper-1.900.1/jasper.spec，

在 jasper-1.900.1 目录下，能找到 asper.spec，所以不会报错；

2. 工作目录改为上一级目录，

在 jasper-1.900.1/../ 目录下，能找到 jasper-1.900.1/jasper.spec，所以不会报错；


## git patch 解释
patch 文件格式：

diff --git a/jasper-1.900.2/jasper.spec b/jasper-1.900.2/jasper.spec

当前在 jasper-1.900.2 所在目录，执行 git apply < jasper-patch/jasper-1.900.2.patch

ls

jasper-1.900.2

因为 git 会自动去掉 a/ 目录，所以在当前目录下能找到 jasper-1.900.2/jasper.spec，不会报错
