so how use findstr regular expression on windows collect bssid result? tried adb shell dumpsys wifi | findstr /r "[0-9a-f]{2}(:[0-9a-f]{2}){5}" nothing

regular expression support findstr limited , not support features of regular expression implementation in perl interpreter, or regular expression class in boost library, or javascript regexp object supports. support regular expressions in perl syntax, implementations , features different. run in command prompt window findstr /? displayed of console application , regular expressions supported findstr.

but findstr designed output line containing found string , not found string. not make sense non regular expression search in file output found string equal search string, perhaps exception of case in case of using option /i , search string containing letters.

therefore suggest use command for mac address written text file.

@echo off rem delete perhaps existing output file.  if exist macaddress.txt del macaddress.txt  rem run command wifi data, skip first line of output, , rem write output file first data column mac addresses.  /f "skip=1" %%i in ('adb.exe shell dumpsys wifi') echo %%i>>macaddress.txt

for understanding used commands , how work, open command prompt window, execute there following commands, , read entirely pages displayed each command carefully.

  • del /?
  • echo /?
  • for /?
  • if /?

see microsoft article using command redirection operators explanation of >>.

routes - Laravel 4 Wildcard Routing to Different Controllers -

-
realizing i'm going take beating this, have several questions "best practices" when constructing laravel route. do laravel routes run "first come first serve" top bottom? if route found, pass control controller (or perform action) , terminate? i have part of application acts url shortner. so, route looks this: route::get('/{id}', array('as' => 'home.text', 'uses' => 'homecontroller@text'), function($id){ //make sure id exists before pushing controller. if (storage::where('shortcode','=', $id)->count() > 0) { // route found } }); how can improved? one, i'm not sure how pass processing on controller conditionally.. sort of controller::make() ..? 3) there better way in laravel check if record exists versus doing mode::where('column','=','value')->count() 4) have legacy urls http://url.com/?...
