Works under Windows, too, if you install the GNU Win32 Utilities ...

C:\PHA Scripts>mminfo -a -r volume | wc -l
847

C:\PHA Scripts>mminfo -a -r volume | sort | uniq | wc -l
847

Our barcodes are our volume labels.


C:\PHA Scripts>mminfo -a -r barcode | wc -l
847

C:\PHA Scripts>mminfo -a -r barcode | sort | uniq | wc -l
491

Now, that's strange ....


C:\PHA Scripts>mminfo -a -r volid | wc -l
847

C:\PHA Scripts>mminfo -a -r volid | sort | uniq | wc -l
847
