windows - 在管道上为变量添加“如果参数”

我刚开始写代码和批处理文件。我试图通过允许用户发出以下批处理文件来自动设置用户：
已执行命令“bvt_audio decode_setup.bat v:\wp\bvt\audio\decode 10.42.233.237”

@echo off
::Conditions leading to errors if the batch script is not executed correctly
if "%1"=="" and "%2"=="" goto error1
if "%1"=="" goto error2
if "%2"=="" goto error3

::Allows user to set the "Source Path" to copy the testcase files from
set source=%1
::Allows user to set the "Destination Path" to copy the testcase files from
set IP_Address=%2

::Tells the user what the "Source" and "Destination" Paths are
echo Source Path = %1
echo Destination Path = %2
echo.
powershell.exe -File "bat_script.ps1" %1 %2 -NoProfile -NoExit


goto end
:error1
echo.
echo Error Syntax: BVT_AudioDecode_Setup.bat "Source_Path\AudioDecode_Testcase_Folder" "Device IP Address"
echo.
echo For example: BVT_AudioDecode_Setup.bat V:\WP\BVT\Audio\Decode 10.42.233.237
echo              -or-
echo              BVT_AudioDecode_Setup.bat C:\WP\BVT\Audio\Decode 10.42.233.237
echo.
echo.
goto end
:error2
echo.
echo Error Syntax: BVT_AudioDecode_Setup.bat "Source_Path\AudioDecode_Testcase_Folder" "Device IP Address"
echo.
echo For example: BVT_AudioDecode_Setup.bat V:\WP\BVT\Audio\Decode 10.42.233.237
echo              -or-
echo              BVT_AudioDecode_Setup.bat C:\WP\BVT\Audio\Decode 10.42.233.237
echo.
echo.
goto end
:error3
echo.
echo Error Syntax: BVT_AudioDecode_Setup.bat "Source_Path\AudioDecode_Testcase_Folder" "Device IP Address"
echo.
echo For example: BVT_AudioDecode_Setup.bat V:\WP\BVT\Audio\Decode 10.42.233.237
echo              -or-
echo              BVT_AudioDecode_Setup.bat C:\WP\BVT\Audio\Decode 10.42.233.237
echo.
echo.
goto end
:end

这是经过测试的，而且有效。
现在我试图添加/测试一个简单的代码块，但找不到正确的语法。是的，我已经用谷歌搜索了3个小时了。我想做的是：
command executed=“random.bat c:\用户”
command executed=“random.bat c:\无效目录”

::Conditions leading to errors if the batch script is not executed correctly
@ECHO OFF
SET "mypath=%1"
ECHO %mypath%
cd %mypath% | find "%invalidpath%"
Echo %invalidpath%

If "%invalidpath%=The system cannot find the path specified." (
goto error1)
else (
goto BeginTest)

::Begins the testcase
:BeginTest
::Do some stuff
goto end
:error1
echo Error: Invalid Path
goto end
:end

如果有人能指点我正确的方向，我将不胜感激…

最佳答案

您可以使用if-exist语句检查目录是否存在。例如，要测试c:\ win，然后更改为c:\ win（如果存在）：

C:
IF NOT EXIST "C:\WIN\." GOTO NOWINDIR
CD \WIN
:NOWINDIR
