NAME
       findfs - find a filesystem by label or UUID

SYNOPSIS
       findfs NAME=value

DESCRIPTION
       findfs will search the block devices in the system looking for a
       filesystem or partition with specified tag. The currently supported
       tags are:

       LABEL=<label>
           Specifies filesystem label.

       UUID=<uuid>
           Specifies filesystem UUID.

       PARTUUID=<uuid>
           Specifies partition UUID. This partition identifier is supported
           for example for GUID Partition Table (GPT) partition tables.

       PARTLABEL=<label>
           Specifies partition label (name). The partition labels are
           supported for example for GUID Partition Table (GPT) or MAC
           partition tables.

       If the filesystem or partition is found, the device name will be
       printed on stdout.

       The complete overview about filesystems and partitions you can get for
       example by

          lsblk --fs

          partx --show <disk>

          blkid

       -h, --help
           Display help text and exit.

       -V, --version
           Print version and exit.

EXIT STATUS
       0
           success

       1
           label or uuid cannot be found

       2
           usage error, wrong number of arguments or unknown option

ENVIRONMENT
       LIBBLKID_DEBUG=all
           enables libblkid debug output.
