Linux lsmod Command
The Linux lsmod (short for list modules) command is used to display the modules that are currently loaded into the system.
Executing the lsmod command will list all the modules loaded into the system. The Linux operating system kernel is modular in nature, so when compiling the kernel, it is not necessary to include all functionalities within the kernel itself. These functionalities can be compiled into separate modules and loaded as needed.
Syntax
