lsblk − list block devices
lsblk [options]
lsblk [options] device...
lsblk lists information about all or the specified block devices. The lsblk command reads the sysfs filesystem to gather information.
The command prints all block devices (except RAM disks) in a tree-like format by default. Use lsblk --help to get a list of all available columns.
−a, −−all
List all block devices.
−b, −−bytes
Print the SIZE column in bytes rather than in human-readable format.
−d, −−nodeps
Don’t print device holders or slaves. For example "lsblk --nodeps /dev/sda" prints information about the sda device only.
−D, −−discard
Print information about the discard (TRIM, UNMAP) capabilities for each device.
−e, −−exclude list
Exclude the devices specified by a comma-separated list of major device numbers. Note that RAM disks (major=1) are excluded by default.
−f, −−fs
Output info about filesystems. This option is equivalent to "-o NAME,FSTYPE,LABEL,MOUNTPOINT". The authoritative information about filesystems and raids is provided by the blkid(8) command.
−h, −−help
Print a help text and exit.
−i, −−ascii
Use ASCII characters for tree formatting.
−m, −−perms
Output info about device owner, group and mode. This option is equivalent to "-o NAME,SIZE,OWNER,GROUP,MODE".
−l, −−list
Use the list output format.
−n, −−noheadings
Do not print a header line.
−o, −−output list
Specify which output columns to print. Use --help to get a list of all supported columns.
−P, −−pairs
Use key="value" output format.
−r, −−raw
Use the raw output format.
−t, −−topology
Output info about block device topology. This option is equivalent to "-o NAME,ALIGNMENT,MIN-IO,OPT-IO,PHY-SEC,LOG-SEC,ROTA,SCHED".
For the partitions are some information (e.g. queue attributes) inherited from parental device.
