What utility allows you to remove modules and also unload them along with their dependencies?

The utility that allows you to remove modules and also unload them along with their dependencies is modprobe. This command is designed to handle kernel modules more intelligently than simply using removal commands on their own.

When you use modprobe to remove a module, it considers any dependencies that the module may have, meaning that if other modules depend on the one you're trying to remove, modprobe will automatically take care of unloading those dependent modules as well. This helps maintain kernel stability and prevents issues that could arise from manually unloading modules without regard to their relationships.

In contrast, other commands like rmmod are more straightforward and can only remove a specified module without considering dependencies. Likewise, insmod is used to insert modules rather than remove them, and lsmod simply lists the currently loaded modules but does not perform any manipulation on them. The ability to intelligently manage module dependencies is a key feature that defines why modprobe is the correct answer in this scenario.
