如果批量存在 [英] If Exist And Else in batch

问题描述

我如何在其中添加和其他选项说:
您没有Java开发工具包，请选择选项4?

How would I add and Else option into this to say:
You don't have the java dev kit please select option 4?

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

推荐答案

您需要先搜索所有子目录，以确定其是否存在.

You need to search fist all subdirectories to decide if it's there.

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
)
