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 /?
