Which command allows you to insert a single module into the Linux kernel?

The command that allows you to insert a single module into the Linux kernel is "insmod." This command is specifically designed for loading a module into the kernel, where it can then be utilized by the system. When you use "insmod," it directly inserts the specified module file into the kernel, ensuring that any dependencies are resolved manually beforehand.

In contrast, "modprobe" is a more sophisticated command that not only adds a module but also automatically handles dependencies by loading other modules that the specified module requires. "rmmod" serves a different function; it is used for removing modules from the kernel rather than inserting them. "depmod" is utilized for generating modules.dep files which contain information about module dependencies, but does not actually load or unload modules.

Thus, "insmod" is the correct choice when the goal is to insert a single module directly into the Linux kernel without automated dependency resolution.
