Linux Find Out Kernel Module (Device Driver) Version Number

Posted on in Categories last updated June 10, 2011

How do I find the version of a kernel module (*.ko files located in /lib/modules/… directory) in Linux server?

You need to use the modinfo command to display information about a Linux Kernel module. The syntax is as follows:

modinfo Module-Name-Here

To list loaded modules, enter:
# lsmod
# lsmod | less

Sample outputs:

  1. Hi, can we know the version of the module without actually loading it?

    actually if i have an rpm and i want to check the actual version of the module, lets say by extracting the rpm and then using the .ko file present in it to check the version.

    1. modinfo can be given a .ko file as the argument to report on.

      #modinfo /tmp/nvme.ko
