如果存在批次

Question

我將如何添加和其他選項到這個說：
你沒有java開發工具包請選擇選項4？

FOR /R "C:\Program Files" %%a IN (.) DO (
    IF EXIST "%%~a\javac.exe" ECHO You Have The Java Dev Kit Ignore Option 4 
) 

Answer 1

您需要搜索所有子目錄以確定它是否存在。

set found=0 
FOR /R "C:\Program Files" %%a IN (.) DO (
    IF EXIST "%%~a\javac.exe" set found=1 
) 
if %found%==0 (
    ECHO You don't have the java dev kit please select option 4 
) ELSE (
    echo Found javac.exe 
) 

Answer 2

SET found=0 
FOR /R "C:\Program Files" %%a IN (.) DO (
    IF EXIST "%%~a\javac.exe" (ECHO You Have The Java Dev Kit Ignore Option 4 
    SET found=1) 
) 
IF %found%==0 (ECHO You don't have the java dev kit please select option 4) 

如果你想ELSE必須使用(和)支架。
