lsmod

The command line tool "lsmod" is a powerful utility used in Unix-like operating systems to display the status of loaded kernel modules. It stands for "List Modules" and provides a user-friendly way to view the dynamically loaded modules in the Linux kernel. When executed without any arguments, it prints a list of all currently loaded modules, including their names, sizes, and the number of references to each module. Typically, the output includes information such as the module's name, memory footprint, state, and the other modules it depends on. The "lsmod" command is often used in conjunction with other tools to troubleshoot system-related issues or to understand the hardware drivers and kernel modules loaded in a particular system. Additionally, it is frequently utilized by developers and system administrators to examine the currently loaded modules and identify any issues or conflicts between them. Overall, "lsmod" is a handy command line tool that assists in gaining insights into the modules loaded in the Linux kernel and diagnosing potential system-related problems.
