"I have here a list of some of the most important Linux file directories (with description) that I hope will serve as a guide for newbies:
/bin
-Contains binaries needed for the boot process and for the system to run. Essential commands such as cd, ls, and more can be found here.
/boot
-Holds files used throughout the boot process along with the Linux kernel itself.
/dev
-Contains device files for all hardware devices on the system."
