我如何知道补丁命令是否有效？

Question

我正在尝试应用一个补丁，这是由寻求-为android项目提供的代码，我从Cyanogenmod下载。用make编译成功的代码，所以我知道所有的文件都在那里。我只是无法了解补丁在做什么，或者它是否工作。我尝试了-verbose选项。我不知道修补程序遍历目录和查找要更新的文件需要多长时间。我看不到cpu里有什么活动。下面是我所看到的说明：在这里输入链接描述，这是我看到的屏幕截图：

   root@ubuntu:~/android/system# ls
    abi       cm-11-2      docs             Makefile   sdk
    android   cm-11-3      external         ndk        smartcard-api-3_1_0
    art       cts          frameworks       out        smartcard-api-3_1_0.tgz
    bionic    dalvik       hardware         packages   system
    bootable  developers   kernel           pdk        tools
    build     development  libcore          prebuilt   vendor
    cm-11     device       libnativehelper  prebuilts
    root@ubuntu:~/android/system# cd smartcard-api-3_1_0
    root@ubuntu:~/android/system/smartcard-api-3_1_0# cd ..
    root@ubuntu:~/android/system# patch -p1 smartcard-api-3_1_0/smartcard-api.patch   ^C
     root@ubuntu:~/android/system# patch -p1 -R smartcard-api-3_1_0/smartcard- api.patch 
    ^C
    root@ubuntu:~/android/system# patch -p1 -verbose smartcard-   api-3_1_0/smartcard-  
    api.patch 
    patch 2.6.1

我认为在某些情况下，我应该寻找目标文件？下面的输出似乎表明一个修补程序是成功的，而另一个文件没有找到？我想我必须找到目标文件并指定它？由于某些原因，即使是完整的路径也不被识别。

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

File to patch: 

Answer 1

由于某些原因，必须通过重定向将补丁文件输入修补程序，即

     patch file

不管用，但是

    patch < file

作品

Answer 2

您可以使用-i选项而不是直接使用重定向：

$ patch -i /path/to/file.patch
