If you find yourself using the Windows command line and are overwhelmed by the number or rows a command returns, you can filter the output so it only returns rows that match your criteria. To do this you use the findstr command: (https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/findstr)
To match on a simple string you use the /C switch and pass the string
example: netstat -oan | findstr /C:"abcd"
this will return all rows with "abcd" in it
If you want to be more fancy you can use the switch /R and it will evaluate the string you are searching for as a regular expression.
