批处理文件问题，收到“文件名，目录名称或卷标签语法不正确”

Question

运行批处理文件时，我收到以下错误 “文件名，目录名称或卷标签语法不正确”

我的批处理文件运行正常，但此错误弹出25次然后继续。我无法弄清楚我在这里缺少什么。以下是我的代码：

::This batch file is used to set a static IP and launch Windows Recovery Environment

@setlocal enableextensions enabledelayedexpansion
@echo off

::Setting Static IP Address & DNS Address

netsh interface ipv4 set address "Local Area Connection" static 10.11.111.110 255.255.255.0 10.11.111.249 1

netsh interface ipv4 set dns "Local Area Connection" static 10.11.101.1 primary

::Verify Network Connection

:chklink

set ipaddr=10.11.107.20

set oldstate=neither

set state=down

for /f "tokens=5,7" %%a in ('ping -n 1 !ipaddr!') do (

    if "x%%a"=="xReceived" if "x%%b"=="x1," set state=up
)

if not !state!==!oldstate! (

    echo.Link is !state!

    set oldstate=!state!

)

REM ping -n 2 127.0.0.1 >nul: 2>nul:


SET answer=!state!

IF %answer%==up (

goto recovery


) ELSE (

IF %answer%==down (
::Set static address on NIC 2 if NIC 1 failed

netsh interface ipv4 set address "Local Area Connection 2" static 10.11.111.110 255.255.255.0 10.11.111.249 1

netsh interface ipv4 set dns "Local Area Connection 2" static 10.11.101.1 primary

goto chklink


)
)

::Launch Windows Recovery Environment

:recovery

cls

x:\sources\recovery\recenv.exe

exit

任何帮助都会很棒！

谢谢！

Answer 1

尝试取出::条评论并将其替换为rem条评论。过去我使用if等内部控制结构时遇到了困难。

有关说明，请参阅here。实际上whole site对cmd.exe脚本编写者来说是一个令人难以置信的资源，由于某种原因，他们不允许安装CygWin。

如果不这样做，请注释@echo off并查看出现这些错误时的操作。
