Linux lsmod command

Linux Command大全

The Linux lsmod (full English name: list modules) command is used to display the modules loaded into the system.

Executing the lsmod command will list all modules loaded into the system. The Linux operating system has a modular feature, so all functions must be placed into the core when compiling the core. You can compile these functions into individual modules and load them separately as needed.
