I know you can do:

sudo modprobe -v some_module

to check the version of /lib/modules/.../some_module.ko, but I'd still like to be able to check the version of any arbitrary kernel module that's not necessarily going to be loaded by modprobe.


modinfo - program to show information about a Linux Kernel module


modinfo module-file

General tip: At the bottom of a manpage and there is a section called "See Also". For modprobe, it lists modinfo. That section can be extremely useful.

  • Curious why this doesn't work for me. It complains it can't find the file even though I checked it exists. – Pavel Šimerda Aug 20 '18 at 11:52


strings some_module.ko | grep vermagic

Or use as mentioned by Ian Kelling modinfo.

  • I need this on a system without 'modinfo', so this was a good tip. For me, the command 'strings some_module.ko | grep version' actually returned the version of my module. – noisygecko Nov 6 '15 at 20:08
