LSBLK(8) System Manager's Manual LSBLK(8)NAME
lsblk - list block devices
SYNOPSIS
lsblk [options]
lsblk [options] device...
DESCRIPTION
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.
OPTIONS -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.
-e, --exclude list
Exclude the devices specified by a comma-delimited 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.
-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".
