lsmod is a Linux command that shows information about all loaded modules.

The format is name, size, use count, list of referring modules. The information displayed is identical to that available from /proc/modules.

If the module controls its own unloading via a can_unload routine then the user count displayed by lsmod is always -1, irrespective of the real use count.
