A Linux administrator is testing a newly developed kernel module for a proprietary hardware device. The module file, special_pci_driver.ko, is located in a temporary development directory and has not yet been integrated into the system's standard module path or dependency database. The administrator needs to load this single module for an immediate, isolated functionality test, intentionally bypassing any dependency checks or automatic loading of related modules. Which command is designed for this direct and specific purpose?
The insmod command is used to insert a kernel module directly from a specified file path, without automatically handling dependencies. This makes it ideal for testing or loading modules that are not yet part of the system's managed module tree. The modprobe command, in contrast, is a more sophisticated tool that loads modules by name and automatically resolves and loads their dependencies from standard locations. lsmod is used to list currently loaded modules, and modinfo displays information about a module file, but neither command loads modules. Therefore, for loading a single module file directly, insmod is the correct choice.
