What command is used to insert a module and its dependencies?

The command used to insert a module and its dependencies is modprobe. This command not only inserts the specified module but also ensures that any other modules that the specified module depends on are loaded beforehand. This is particularly useful in complex kernel module environments where certain modules are interdependent.

In contrast, the insmod command can be used to insert a module but does not handle dependencies. If a module requires another module to be present and that module hasn’t been loaded yet, insmod will fail.

The lsmod command is used to display the currently loaded modules, providing a list of all active kernel modules but does not insert or manage them.

Lastly, the rmmod command is utilized to remove modules from the kernel, which is the opposite of what inserting a module entails. Hence, modprobe is the most suitable choice when considering the need for dependency resolution along with inserting a module.
