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. If the input is not
in the format of NAME=value, then the input will be copied to the output without any modification.
