Blkid command on Linux (shows block device attributes)

The blkid command on Linux shows what type of content a block device (disks) contains and its attributes such as device name, and other metadata.

If a device is entered, it will show only the information for the specific device. If no parameters are entered, it will show information from all connected block devices.

Example:

# blkid <br></br>/dev/sda1: uuid="1C3B15B1-cd13-4a73-b2a8-449fa3aa039f” Type="xfs” <br></br>/dev/sda2: uuid="gzxwoc-7zia-ade3-zfwd-sugd-8hk3-j003qr” type="lvm2_member” /dev/mapper/cl-root: uuid="lvm2_member” <br></br>/dev/mapper/cl-root: uuid:UUID="lvm2_member” /dev/mapper/cl-root ="602fcf7d-d716-4f5b-aa6b-fb34d85c0169" type="XFS” <br></br>/dev/mapper/cl-swap: uuid="a 873901e-5b33-4c78-84f5-e9eeadd9fba3" type="swap”

/dev/mapper/cl-home: uuid=“fcbdceb1-9053-460b-908c-f7913f91dbe6” type=“XFS” It also shows information about the disk topology:

$ sudo blkid -i /dev/sda1 devName=/dev/sda1 MINIMUM_IO_SIZE=4096 PHYSICAL_SECTOR_SIZE=4096 LOGICAL_SECTOR_SIZE=512
