Find Out Linux Kernel Modules ( Drivers ) Location / Directory
Q. Can you tell me exact location of Linux kernel driver under Linux file system? Where to find all available modules?
A. /lib/modules/kernel-version/ directory stores all compiled drivers under Linux operating system. You can use modprobe command to intelligently add or remove a module from the Linux kernel. modprobe looks in the
module directory /lib/modules/$(uname -r) for all the modules and other files, except for the optional /etc/modprobe.conf configuration file and /etc/modprobe.d directory. Type the following command to display current modules:
$ ls -l /lib/modules/$(uname -r)
Sample output:

You can change directory by typing following command:
