'lsblk' - list block devices - Video Man Pages

The 'lsblk' command is used to list your block devices (drives) on your system.

- List all storage devices (that aren't empty) in a tree-like format:
lsblk

- List all devices including empty devices:
lsblk -a

- Print sizes in bytes rather than in human-readable format:
lsblk -b

- Output info about filesystems:
lsblk -f

- Exclude the devices specified by the MAJ device number:
lsblk -e 7

NOTE The above removes loopback devices, which is useful if you want to filter out snaps from 'lsblk' output.

- Exclude the devices specified by the comma-separated list of MAJ device numbers:
lsblk -e 7,8

- Specify columns for the output using a comma-separated list:
lsblk -o NAME,SERIAL,MODEL,TRAN,TYPE,SIZE,FSTYPE,MOUNTPOINT

- Specify and additioanl column added to the default output:
lsblk -o +UUID

- Output info about device topology:
lsblk -t

NOTE The above is equivalent to...
'-o NAME,ALIGNMENT,MIN-IO,OPT-IO,PHY-SEC,LOG-SEC,ROTA,SCHED,RQ-SIZE,RA,WSAME'

- Output info about topology and sort by column name:
lsblk -t -x SCHED

- Use ASCII characters for tree formatting:
lsblk -i
