在提示中输入 space 崩溃批处理文件

Question

出于无聊，我正在尝试完全复制命令行，但我遇到了问题。这是我的代码：

@echo off
set /a secret=1
color B
title Subnet Access v1.0
echo   ____________________________________________________________
echo  /                                                            I
echo I                     Subnet Access v1.0                      I
echo I____________________________________________________________/
echo.
echo.

echo alert 0-21-77
timeout 1 >NUL
echo. 
set /p pid=enter pid: || set pid=empty

IF "%pid%"=="1123321231" (
    echo.
    set /a "secret+=1"
    cls
    echo Secrets %secret%/10 found.
    timeout 3 >NUL
    cls
    echo.
    echo pid confirmed

    cls
    echo.

    goto :unidentify
    )
IF NOT "%pid%"=="1123321231" GOTO :unidentify
:unidentify

set /p commandMur=sys/dev/: $^> || set commandMur=emptycom
    )
IF %commandMur%==help (
    ::help segment
    echo.
    echo Help v0.1 Alpha by Murtaugh
    echo.
    echo Commands are listed below:
    echo dir - Lists your directory's contents.
    echo help - Shows this page.
    echo connect - Connects you to an IP address.
    echo.
    goto :sub01
    )
IF "%commandMur%"=="exit" (
    goto :eof
    )
IF "%commandMur%"=="cls" (
    cls
    goto :sub01
    )
IF "%commandMur%"=="su" IF "%su%"=="0" (
    cls
    echo.
    set /a "secret+=1"
    echo Secrets %secret%/10 found.
    set su=1
    goto :sub01
    )
IF "%commandMur%"=="su" IF "%su%"=="1" (
    goto :sub01
    )
IF "%commandMur%"=="emptycom" (
    goto :sub01
    )
IF NOT "%commandMur%"=="exit" IF NOT "%commandMur%"=="help" IF NOT "%commandMur%"=="cls" IF NOT "%commandMur%"=="su" (
    echo "%commandMur%": Bad command or file name
    echo.
    goto :sub01
    ) ::PROBLEM ENDS HERE

但是当我输入带空格的内容时，它会显示 test==exit was unexpected at this time. 并关闭。无论如何我可以解决这个问题吗？谢谢

编辑：试过 "%prompt%"=="test" 东西，不起作用。

Answer 1

我不是一个真正优秀的程序员，但尝试在键入带空格的文本时添加 "QUOTATION TAGS"，因为批处理有时会对这些空格感到困惑

Answer 2

test==exit was unexpected ... 是 if 的典型语法错误（set 不会出现此类错误）。

您很可能在下一行有一个 if %command%==exit ...-命令。为避免语法错误，写 if "%command%"=="exit" ...
