i want read stdin filename batch file need create. in single line , using pipe. when try cmd creating .bat before put in name. set /p filename= | copy nul %a%.bat that's not how pipe works. pipe takes output of previous command, , makes input of next command. set /p filename= command doesn't produce output, copy nul %a%.bat doesn't input, that's irrelevant anyway, because copy command doesn't take input anyway. copy nul %a%.bat command creates empty file called .bat because haven't defined variable called a , , %a% gets expanded empty string. what want requires 2 commands: set /p filename= copy nul %filename%.bat

there difference between app.use(function(req,res,next){ }); and router.use('/some_route', function(req,res,next){ }); ...the difference being app.use runs every request , router.use runs matching routes. my question router must lie underneath app. surely app has default router internal it. there way access router...app.router? thought deprecated? secondly, looking way access current router being used. for example, app.use(function(req,res,next){ var currentrouter = req.app._router // (?) }); or router.use(function(req,res,next){ var currentrouter = req._router //(?) }); where req._router equal same router router.use call of course. in latest express code , default app router in app._router . it created lazily means it's not created until route defined (with app.use() or app.get() or that). it not appear meant public property , subject change. can, of course, define own router root path , use
