Try using this way, which was its intended usage:
blkid -o value -s TYPE -t UUID=a3dc6f56-da22-4079-bf75-1fa2ce1aa4b0
(replace part following -t with the search criteria you want; for
example, "-t LABEL=backup").
It was intended to be used a script-friendly way, and I believe there
are shell scripts using in this fashion. So please don't change blkid
-o value.
Best regards,
