Which command displays the currently loaded modules in Linux?

The command used to display the currently loaded modules in Linux is indeed 'lsmod'. This command lists all the kernel modules that are currently loaded into the Linux kernel. Each entry in the output shows details about the modules, including their name, size, and usage count, allowing users to see which modules are active and interacting with the system.

Understanding this command is essential for troubleshooting and system management tasks, as it provides insights into the kernel's current configuration and the drivers that are in use. The other commands serve different purposes: 'modprobe' is used to add or remove modules, 'insmod' is specifically for inserting a module into the kernel, and 'rmmod' is utilized to remove a module from the kernel. These functionalities are crucial for managing kernel modules but do not serve the purpose of displaying currently loaded modules.
