Count of items matching a search criteria

[georgejones314]

I'm building a simple batch file to compare the total count of files in a directory to the count of files matching -if "$track". if track is present then i have listened to the item (mp3)... and if the total count for track = total items then i have finished the album (directory).

Is there a simple way to count the items that match the -if "$track" criteria?

Thanks

Sorry if this is obvious, but I spent the appropriate amount of time searching the documentation and forum and came up empty handed.

I think the easiest way would be to pipe the exiftool output into grep (or find for windows) and take the "files read" line that appears at the end. 

exiftool -if "$track" -PlaceholderTag FileOrDir | grep "files read"

Replace grep with find for windows.  I just put "PlaceholderTag" in there as a fake tag to limit the output of exiftool.

Thanks I'll give it a try and report back.

The following subroutine worked, but yuch! I hate writing to a temporary file in a batch process. But since I only run this once a year or so, it's not that big a deal.

Thx
