       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.

       -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

       -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

       -r, --raw
	      Use the raw output format.

       -t, --topology
	      Output  info  about  block  device  topology.   This  option  is	equivalent to "-o
