在批处理文件中使用 AND 条件会导致问题
在我打开 echo 的批处理文件中
findstr SWITCHIDENTITY rf_monitor.out >nul 2>&1 && set IDENTITY_FOUND=true
findstr SWITCHUTILITY rf_monitor.out >nul 2>&1 && set UTILITY_FOUND=true
findstr "GP Manager connection successful" rf_monitor.out >nul 2>&1 && set GPMANAGER_FOUND=true
，下面是我看到的内容
D:\cvstags\trunk\regfortcms\install\win\scripts>findstr SWITCHIDENTITY rf_monito r.out 1>nul 2>&1 && set IDENTITY_FOUND=true D:\cvstags\trunk\regfortcms\install\win\scripts>findstr SWITCHUTILITY rf_monitor .out 1>nul 2>&1 && set UTILITY_FOUND=true D:\cvstags\trunk\regfortcms\install\win\scripts>findstr "GP Manager connection s uccessful" rf_monitor.out 1>nul 2>&1 && set GPMANAGER_FOUND=true **&& was unexpected at this time.**
为什么我会得到 &&这时候出乎意料？如果我自己在 DOS 提示符下键入这三个命令，我不会收到任何此类消息。请指教。
In a batch file I have
findstr SWITCHIDENTITY rf_monitor.out >nul 2>&1 && set IDENTITY_FOUND=true
findstr SWITCHUTILITY rf_monitor.out >nul 2>&1 && set UTILITY_FOUND=true
findstr "GP Manager connection successful" rf_monitor.out >nul 2>&1 && set GPMANAGER_FOUND=true
with echo on, below is what I see
D:\cvstags\trunk\regfortcms\install\win\scripts>findstr SWITCHIDENTITY rf_monito r.out 1>nul 2>&1 && set IDENTITY_FOUND=true D:\cvstags\trunk\regfortcms\install\win\scripts>findstr SWITCHUTILITY rf_monitor .out 1>nul 2>&1 && set UTILITY_FOUND=true D:\cvstags\trunk\regfortcms\install\win\scripts>findstr "GP Manager connection s uccessful" rf_monitor.out 1>nul 2>&1 && set GPMANAGER_FOUND=true **&& was unexpected at this time.**
Why do I get that && was unexpected at this time? If I type the three commands myself on the DOS prompt I don't get any such message. Please advice.

该死，错误消息不是关于我发布的行，而是关于我对 && 的使用。在 IF 条件下。看来我必须使用像 IF 条件1 IF 条件2 。
Goddammit, the error message had been not about the lines I posted but about my usage of && in an IF condition. It seems that I have to use like IF condition1 IF condition2 .
