NAME         top

       findfs - find a filesystem by label or UUID

SYNOPSIS         top

       findfs TAGNAME=value

DESCRIPTION         top

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

          LABEL=label
              Specifies a filesystem label.

          UUID=uuid
              Specifies a filesystem UUID.

          PARTUUID=uuid
              Specifies a partition UUID. Partition identifiers are
              supported for example for GUID Partition Table (GPT)
              partition tables.

          PARTLABEL=label
              Specifies a partition label (name). Partition labels
              are supported for example for GPT and MAC partition
              tables.

       If the filesystem or partition is found, the device name will be
       printed on stdout. If the input is not in the format of
       TAGNAME=value, then the input will be copied to the output without
       any modification.

       You can get a complete overview about the filesystems and
       partitions in the system with one of the following commands:

          lsblk --fs

          partx --show disk

          blkid
