Which command is employed to remove modules with or without dependencies?

The command that is used to remove modules, regardless of whether they have dependencies or not, is the one that includes the -d option. This option indicates that you want to remove a module and any dependencies associated with it, making it effective for cleaning up the module environment.

The functionality of this command ensures that not only is the targeted module removed, but also any other modules that depend on it are considered for removal as well. This is particularly useful in scenarios where module interdependencies could prevent a straightforward removal. By using this command, system administrators can maintain system integrity while effectively managing kernel modules.

The other options, while related to managing kernel modules, do not serve the function of removing modules in this manner. For instance, commands regarding installation or alias management do not impact the removal of modules or their dependencies. This specificity is crucial for nuanced kernel management, which is a key aspect of effective system administration in Linux environments.
