How do I resolve '@echo' is not a recognized command
提问by Mike Roosa
I've implemented Scott Hanselman's method for keeping up with a dev/qa/prod version of web.config: http://www.hanselman.com/blog/CommentView.aspx?guid=93bfa4b3-44cd-4681-b70e-f4a2b0386466
我已经实施了 Scott Hanselman 的方法来跟上 web.config 的 dev/qa/prod 版本：http: //www.hanselman.com/blog/CommentView.aspx?guid=93bfa4b3-44cd-4681-b70e-f4a2b0386466
For some reason when I compile my project I get this error message in my output window.
Any ideas?
出于某种原因，当我编译我的项目时，我在输出窗口中收到此错误消息。
有任何想法吗？
------ Build started: Project: ABC.Flims.Web, Configuration: Development Any CPU ------

'@echo' is not recognized as an internal or external command,
operable program or batch file.
Here is the script file:
这是脚本文件：
@echo off
echo Comparing two files: %1 with %2
if not exist %1 goto File1NotFound
if not exist %2 goto File2NotFound
fc %1 %2
if %ERRORLEVEL%==0 GOTO NoCopy
echo Files are not the same. Copying %1 over %2
copy %1 %2 /y & goto END
:NoCopy
echo Files are the same. Did nothing
goto END
:File1NotFound
echo %1 not found.
goto END
:File2NotFound
copy %1 %2 /y
goto END
:END
echo Done.

The file is probably Unicode encoded and has a Byte Order Mark(BOM) at the start that is throwing off the batch processor.
该文件可能是 Unicode 编码的，并且在开始时有一个字节顺序标记(BOM)，这会导致批处理器失效。
Save it as an ASCII file and you should be OK. You can do this in notepad- select Save As...from the Filemenu and ensure that the Encodingdropdown is set to ANSI.
将其另存为 ASCII 文件，您应该没问题。你可以这样做notepad选择-Save As...从File菜单中，确保Encoding下拉菜单设为ANSI。

Stumbled upon a similar issue. Found that within visual studio, if you open your *.bat file, you can choose File -> Advanced Save Options. From the drop-down menu under encoding, select 'US-ASCII - Codepage 20127'
偶然发现了一个类似的问题。发现在visual studio中，如果你打开你的*.bat文件，你可以选择File -> Advanced Save Options。从编码下的下拉菜单中，选择“US-ASCII - Codepage 20127”

A file named echo.

P:\>echo.
'echo.' is not recognized as an internal or external command,
operable program or batch file.
P:\>del echo

An echo in current folder or in the path will cause this.
当前文件夹或路径中的回声会导致这种情况。
/echo

I think your file is Unicode encoded and needs to be ascii.
我认为你的文件是 Unicode 编码的，需要是 ascii。
