[root@Llawyr ~]# lsblk --help<br />
<br />
Usage:<br />
lsblk [options] [<device> ...]<br />
<br />
Options:<br />
-a, --all print all devices<br />
-b, --bytes print SIZE in bytes rather than in human readable format<br />
-d, --nodeps don't print slaves or holders<br />
-D, --discard print discard capabilities<br />
-e, --exclude <list> exclude devices by major number (default: RAM disks)<br />
-f, --fs output info about filesystems<br />
-i, --ascii use ascii characters only<br />
-I, --include <list> show only devices with specified major numbers<br />
-l, --list use list format output<br />
-m, --perms output info about permissions<br />
-n, --noheadings don't print headings<br />
-o, --output <list> output columns<br />
-p, --paths print complete device path<br />
-P, --pairs use key="value" output format<br />
-r, --raw use raw output format<br />
-s, --inverse inverse dependencies<br />
-S, --scsi output info about SCSI devices<br />
-t, --topology output info about topology<br />
<br />
-h, --help display this help and exit<br />
-V, --version output version information and exit<br />
<br />
