findfs8
Find a filesystem by label or uuid
Usage
findfs TAGNAME=value
Overview
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:
