batch file - Need a way to obtain total instances after finding using FINDSTR -

-

so have far , works finding specified string need echo total number of times it's found.

findstr /c:"\"ma\"" %fn%

thanks in advance.

findstr has no counter, find has (but has no regex).

also findstr /c: searches \"ma\" literally. should add /r (assuming search "ma"). can combine both commands needs: 

findstr /r /c:"\"ma\"" %fn% | find /c /v ""
