为CMD.EXE％ERRORLEVEL％9009官方MS参考 [英] Official MS reference for cmd.exe %errorlevel% 9009

问题描述

所以，我从运行cmd.exe的从一个有效的程序和检查经验，了解％ERRORLEVEL％会返回一个0：

So I know from experience that running a valid program from cmd.exe and checking the %errorlevel% will return a 0:

C:\>dir logo.bmp
 Volume in drive C has no label.
 Volume Serial Number is 5283-A7A2

 Directory of C:\

05/22/2008  12:43 PM         1,440,054 logo.bmp
               1 File(s)      1,440,054 bytes
               0 Dir(s)  71,723,995,136 bytes free

C:\>echo %errorlevel%
0

同样，试图执行一个不存在的命令，然后为％的误差code％检查给了我9009：

Likewise, trying to execute a command that does not exist and then checking for the %errorcode% gives me a 9009:

C:\>idontexist.exe
'idontexist.exe' is not recognized as an internal or external command,
operable program or batch file.

C:\>echo %errorlevel%
9009

我已经写批处理脚本多年，他们一直努力这样。然而，有人问起兼容性这一技术的问题（向前和向后），我无法找到微软实际上定义9009的错误级别时未找到文件或程序的任何正式文件。我来最接近的是这个网站（<一个href=\"http://msdn.microsoft.com/en-us/library/ms681381%28v=vs.85%29.aspx\">http://msdn.microsoft.com/en-us/library/ms681381(v=vs.85).aspx)其中，不幸的是，列出9009作为DNS错误。

I've been writing batch scripts for years and they have always worked this way. However, someone has asked questions about compatibility (both forward and backward) of this technique and I can't find any official documentation from Microsoft actually defining 9009 as the errorlevel when a file or program is not found. The closest I've come is this site (http://msdn.microsoft.com/en-us/library/ms681381(v=vs.85).aspx) which, unfortunately, lists 9009 as a DNS error.

有谁知道这个行为是由Microsoft记录？

Does anyone know where this behavior is documented by Microsoft?

推荐答案

在Exchange的团队做了一个的常见错误查找工具将翻译错误codeS（包括的HRESULT，这是方便）为您。对于9009的输出是：

The Exchange team put out a Common Error Lookup Tool that will translate error codes (including HRESULTs, which is handy) for you. The output for 9009 is:

# for decimal 9009 / hex 0x2331 :
  MSG_DIR_BAD_COMMAND_OR_FILE                                   cmdmsg.h

# 4 matches found for "9009"

...所以你要找的人是从cmdmsg.h。

...so the one you're looking for is from cmdmsg.h.

它不是真正的文件的本身，但它至少官方的。

It's not really documentation, per se, but it's at least official.
