lsmod is a command on Linux systems. It shows which loadable kernel modules are currently loaded.

Abridged example output:

# lsmod
Module                  Size  Used by
af_packet              27392  2

"Module" denotes the name of the module. "Size" denotes the size of the module (not memory used).[1] "Used by" denotes each module's use count and a list of referring modules. The "Used by" list is sometimes incomplete.[2] If the module controls its own unloading via a can_unload routine then the use count displayed by lsmod is always -1, irrespective of the real use count.
