findfs:tldr:7a27a

The command findfs LABEL=${label} is used to locate the filesystem associated with a specified label.

Here's a breakdown of the command:

• findfs is a utility command available in Linux systems for finding the filesystem associated with a particular identifier such as a label, UUID, or device path.
• LABEL=${label} sets the variable label to a specific label value. The LABEL= prefix specifies that the value of the variable is a label rather than a literal string.

When the command is executed, it searches for a filesystem that has the specified label and returns the corresponding device path or identifier. The located filesystem could be on a hard drive, SSD, or other storage devices connected to the system.

For example, if you have a filesystem with the label "mydata" and you run findfs LABEL=mydata, the command will search for a filesystem with the label "mydata" and return the device path or identifier associated with it.
