Which command is used to install a module along with all its needed dependencies?

The command that is used to install a module along with all its needed dependencies is modprobe. This tool is designed specifically for loading kernel modules in Linux systems. When you execute the modprobe command, it automatically handles any dependencies that the module may have. It searches for and loads all the necessary modules in the correct order, which is crucial for ensuring that the module functions correctly and all required dependencies are met.

In comparison, insmod is a more straightforward command that only loads a specified module and does not manage dependencies; it is often seen as a lower-level tool. loadmodule is generally not recognized as a standard command in Linux; it is less common and may vary across different systems or be entirely non-existent. depmod, while it can find dependencies, does not load modules; instead, it is used to generate a list of dependencies for kernel modules, which is used by modprobe to determine which modules are needed. Thus, modprobe is the optimal choice for managing modules and their dependencies efficiently.
