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". AUTHORS

For the partitions are some information (e.g. queue attributes) inherited from parental device. AUTHORS
