CompTIA Linux+ (XK0-006) Cheat Sheet — Kernel Modules

Every command from the Kernel Modules chapter, on one page.

The discovery order (lspci, lsusb, dmesg), lsmod vs modinfo, modprobe vs insmod, how depmod builds the map, how /etc/modules-load.d makes a driver survive reboot — plus the two traps the exam sets with a straight face: insmod for dependencies, and blacklist mistaken for remove.

Free companion to the free chapter on YouTube (@ByteBarExamPrep): "XK0-006: Load the Missing Driver, Device Appears."
