lsmod

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

An example terminal print after running lsmod command:

Module Size Used by af_packet 27392 2 8139too 30592 0 snd_cs46xx 96872 3 snd_pcm_oss 55808 1 snd_mixer_oss 21760 2 snd_pcm_oss ip6table_filter 7424 1 ip6_tables 19728 1 ip6table_filter ipv6 290404 22 xfs 568384 4 sis900 18052 5 libata 169920 1 pata_sis scsi_mod 158316 3 usb_storage,sd_mod,libata usbcore 155312 6 ohci_hcd, usb_storage, usbhid 

"Module" denotes the name of the module. "Size" denotes the size of the module (not memory used) in Bytes.^[1] "Used by" shows that number of times the module is currently in use by running programs. Next to this is a list of other modules which refer to this one. 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.
