Module Setup, Loading And Unloading (Cont.)

'lsmod' is used to print the list of currently loaded modules.

'rmmod' is used to remove a module. The module's use count must be 0 for this to work. 'rmmod' expects the module's name (its file name prefix). A module can be coded so it'll refuse to get unloaded.

'depmod' may be used to create a proper dependency list for 'modprobe'. Using 'depmod -a' will scan all modules under /lib/modules/<kernel-version>/ and produce a Makefile-like dependency list in /lib/modules/<kernel-version>/modules.dep  .
