lsmod
lsmod (list modules) is used to show the status of modules that are loaded in the kernel. lsmod works by listing the /proc/modules but in a more readable way.
Usage
lsmod [options]
-s, --syslog      print to syslog, not stderr
-v, --verbose     enables more messages
-V, --version     show the version
-h, --help        show help
The output is laid out with:
- Module name
- Size in ram
- How many other modules are using that module
- Names of the modules that are using that module
