我制作了一个清理临时文件并加密要加密的文件的程序。我在计算机上收集信息以及添加注册表。
然而，我无法让它正常工作 - 你能看出出了什么问题吗？
问题是“if / i”命令不起作用。我试图调试它但没有看到问题。我已经在cmd中使用errorlevel运行它，但找不到问题。如果您知道问题所在，请告诉我。
P.S。完成后的代码将是EXE，（因此为WOLF.EXE）。我将在安装过程中收集信息，（这将在EULA中提及）。

答案 0 :(得分：0)
if /i %a%==y (goto install) else (goto :error3)
if /i %a%==n (goto :exit) else (goto :error3)
第一行转到:install或:error3。永远不会到达下一行。更好的方法是（根本不需要else）：
if /i %a%==y goto :install
if /i %a%==n goto :exit
goto :error3
注意：当用户按下ENTER时，您将收到语法错误。通过引用比较的两边来避免它：
if /i "%a%"=="y" goto :install
if /i "%a%"=="n" goto :exit
goto :error3
您可能希望切换到choice命令，该命令执行错误处理：
choice /C YN /N /M "Do you agree with the EULA (y/n)"
if errorlevel 2 goto :exit
if errorlevel 1 goto :install
