       [--match-token <token>] [<dev> ...]

 blkid -p [--match-tag <tag>] [--offset <offset>] [--size <size>]
       [--output <format>] <dev> ...

 blkid -i [--match-tag <tag>] [--output <format>] <dev> ...


 -c, --cache-file <file>    read from <file> instead of reading from the default
                              cache file (-c /dev/null means no cache)
 -d, --no-encoding          don't encode non-printing characters
 -g, --garbage-collect      garbage collect the blkid cache
 -o, --output <format>      output format; can be one of:

 -k, --list-filesystems     list all known filesystems/RAIDs and exit
 -s, --match-tag <tag>      show specified tag(s) (default show all tags)
 -t, --match-token <token>  find device with a specific token (NAME=value pair)
 -l, --list-one             look up only first device with token specified by -t
 -L, --label <label>        convert LABEL to device name
 -U, --uuid <uuid>          convert UUID to device name
 <dev>                      specify device(s) to probe (default: all devices)

Low-level probing options:
 -p, --probe                low-level superblocks probing (bypass cache)
 -i, --info                 gather information about I/O limits
 -S, --size <size>          overwrite device size
 -O, --offset <offset>      probe at the given offset
 -u, --usages <list>        filter by "usage" (e.g. -u filesystem,raid)
 -n, --match-types <list>   filter by filesystem type (e.g. -n vfat,ext3)
 -D, --no-part-details      don't print info from partition table
