Question

我无法弄清楚这一点，我真的不知道如何制定这个问题，我希望这已经足够了我正在研究这个实验。当我故意插入无效目录时，我收到消息“系统无法找到指定的路径。”

@echo off
set /a test=0
title Color changer
if exist "Settings/files.bat" (
call Settings/files.bat
) else (
mkdir Settings
echo set savloc=%cd%>Settings\files.bat
call Settings\files.bat
)
if exist "%savloc%\color.bat" (
call "%savloc%\color.bat"
) else (
color 0f
)
set menu=2
goto menu

:menu
cls
echo color : change color
echo cd : change direction
set /p menu=
if "%menu%" == "color" goto setcolor
if "%menu%" == "cd" goto changedir
else goto menu

:changedir
cls
set test=0
echo (current location: %savloc%)
echo What do you want your new location to be?
set /p dir=#
echo set test=1 > "%dir%\testfile.bat"
call "%dir%\testfile.bat"

If EXIST "%dir%\testfile.bat" (
echo Valid Location! (current location: %dir%)
pause >nul
echo set savloc=%dir%> Settings\files.bat
call Settings\files.bat
del "%dir%\testfile.bat"
goto menu
)
iF NOT EXIST "%dir%\testfile.bat" (
echo Invalid Location, Please redo This step. (reset location to: %cd%)
pause >nul
echo set savloc=%cd%> Settings\files.bat
call Settings\files.bat
del "%dir%\testfile.bat"
goto menu
)

goto menu

:setcolor
cls
echo What do you want the color to be?
echo.
set /p clr=#
color %clr%
echo color %clr%>"%savloc%\color.bat"
goto menu

我尝试使用“test”变量，将其保存到该目录然后读取，而不是：

 If EXIST "%dir%\testfile.bat" (

和

 If NOT EXIST "%dir%\testfile.bat" (

但这也行不通。

我真的希望有人可以帮助我。

更新：现在我将声明改为：

if exist "%dir%" (
    echo Valid Location! (current location: %dir%)
    pause >nul
    echo set savloc=%dir%> Settings\files.bat
    call Settings\files.bat
    goto menu
) else (
    echo Invalid Location, Please redo This step. (reset location to: %cd%)
    pause >nul
    echo set savloc=%cd%> Settings\files.bat
    call Settings\files.bat
    goto menu
)

goto menu

但是现在当目录无效时，它只是将它回显到settings \ files.bat中它没有说什么。

在测试目录之前，您正在回复%dir%\testfile.bat 。

当目录无效时，重定向无效，您将收到错误消息。

首先检查目录是否存在。修复示例：

set /p dir=# If NOT EXIST "%dir% ( echo "%dir% does not exist goto menu ) rem now echo has a chance to work echo set test=1> "%dir%\testfile.bat" call "%dir%\testfile.bat"
