[clug] lsblk

[Sam Parkinson]

Ah, lsblk is one of the most useful commands hands down.  It beats
fumbeling around watching /dev/{sd*,mmcblk*} to find what name your
drive gets.
According to this question [1], the /dev/sd* was to keep things in the
place users expected, rather than renaming them.  Interestingly,
/dev/mmcblk*p* seems to be an exception to this rule.
These days, there is also /dev/disk/by-*.  That features disks
catogrized by useful things; such as GUIDs or partition labels.  So it
is better to use, as it is stable across reboots - things aren't just
named based on the order they are mounted.
