NAME
       findfs - find a filesystem by label or UUID

SYNOPSIS
       findfs TAGNAME=value

DESCRIPTION
       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

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

       -V, --version
           Display 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.
