Error message when scanning "Line 1. Usupported escape sequence '\D'"

[KClough]

➜  ./megasd scan /Volumes/MEGASG256GB/2_Sega_CD
Line 1. Usupported escape sequence '\D'.

I'm scanning individual game type subdirectories due to the fact that I get another error when I run on the root:

➜  ./megasd scan /Volumes/MEGASG256GB
open /Volumes/MEGASG256GB/.Spotlight-V100: operation not permitted

Update

I was able to remove .Spotlight-V100 and .Trashes system directories off of my micro sd card, but I still get the same Line 1. Usupported escape sequence '\D'. error whenever I include my Sega CD image directory.

Including the --verbose flag doesn't add any additional info.
