What command can be used to display the label and UUIDs of filesystems?

The command that can be utilized to display the label and UUIDs (Universally Unique Identifiers) of filesystems is blkid. This command retrieves and displays information about block devices, including their file system type, labels, and UUIDs. It is particularly useful for identifying filesystems and their attributes in a system.

When using blkid, the output will typically include details like the device name, its UUID, and any associated labels, which helps in managing and referencing filesystems. This information is crucial for tasks such as configuring fstab for persistent mounting of filesystems after reboots.

Commands like lsblk provide a view of block devices and their mount points but do not display filesystem-specific attributes like UUIDs and labels. The df command focuses on disk space usage and mounted filesystems without detailing their identifiers, while the mount command is used to attach filesystems to the filesystem hierarchy but also lacks the capability to show UUIDs and labels directly. Thus, blkid is the appropriate choice for obtaining detailed filesystem labels and UUIDs.
