如果没有不同的行，您将收到一条消息指示消息。

fc 示例
fc autoexec.bat config.sys
在当前目录中的config.sys和autoexec.bat之间进行文件比较。
fc c:\autoexec.bat c:\config.sys /b
以二进制格式在根目录中的config.sys和autoexec.bat之间进行文件比较。。
fc "C:\Program Files (x86)\A.txt" "C:\Program Files (x86)\B.txt"
如果您的目录或文件名包含空格，则可能需要在完整路径周围添加引号，如本示例所示。
fc autoexec.bat config.sys
Gives a file comparison between the config.sys and the autoexec.bat in the current directory.
fc c:\autoexec.bat c:\config.sys /b
Gives a file comparison between the config.sys and the autoexec.bat in the root directory in binary format.
fc "C:\Program Files (x86)\A.txt" "C:\Program Files (x86)\B.txt"
If your directory or file name has spaces, it may be necessary to add quotes around the complete path as shown in this example.
