Hi,
I have merged Milan's lsblk(8) utility. The command lists information
about all or selected block devices (from /sys). The default output
is like "dmsetup ls --tree", but works with all devices and does not
require root permissions.
The command is very useful if you want to see hierarchy of devices,
especially on machines with DM, MD, mpath, ...

Usage:
lsblk [options] [<device> ...]
Options:
-a, --all print all devices
-b, --bytes print SIZE in bytes rather than in human readable format
-e, --exclude <list> exclude devices by major number (default: RAM disks)
-f, --fs output info about filesystems
-h, --help usage information (this)
-i, --ascii use ascii characters only
-m, --perms output info about permissions
-l, --list use list format ouput
-n, --noheadings don't print headings
-o, --output <list> output columns
-r, --raw use raw format output
-t, --topology output info about topology
Available columns:
NAME device name
KNAME internel kernel device name
MAJ:MIN major:minor device number
FSTYPE filesystem type
MOUNTPOINT where the device is mounted
LABEL filesystem LABEL
UUID filesystem UUID
RO read-only device
RA removable device
MODEL device identifier
SIZE size of the device
OWNER user name
GROUP group name
MODE device node permissions
ALIGNMENT alignment offset
MIN-IO minimum I/O size
OPT-IO optimal I/O size
PHY-SEC physical sector size
LOG-SEC logical sector size
