What command would you use to check detailed information about a kernel module's parameters?

Using the modinfo command is the correct choice for checking detailed information about a kernel module's parameters. This command retrieves and displays metadata about a specific kernel module, including the module's name, description, author, license, version, and various parameters that can be configured. This information is particularly useful for understanding how a module operates and what options are available for its configuration.

The other commands serve different purposes: insmod is used to insert a kernel module into the Linux kernel, rmmod is utilized to remove a module from the kernel, and lsmod lists the currently loaded modules but does not provide detailed parameter information about them. Thus, modinfo is uniquely suited for acquiring comprehensive details regarding a kernel module's parameters.
