• List all storage devices in a tree-like format:

lsblk

• Also list empty devices:

lsblk {{[-a|--all]}}

• Print the SIZE column in bytes rather than in a human-readable format:

lsblk {{[-b|--bytes]}}

• Output info about filesystems:

lsblk {{[-f|--fs]}}

• Use ASCII characters for tree formatting:

lsblk {{[-i|--ascii]}}

• Output info about block-device topology:

lsblk {{[-t|--topology]}}

• Exclude the devices specified by the comma-separated list of major device numbers:

lsblk {{[-e|--exclude]}} {{1,7,...}}

• Add extra information to the output using a comma-separated list of columns (omit the + sign to only display the specified columns):

lsblk {{[-o|--output]}} +{{NAME,ROTA,SERIAL,MODEL,TRAN,TYPE,SIZE,FSTYPE,MOUNTPOINT,...}}
