Modprobe Debian Setup Command Line

Did you know that the modprobe command in Debian helps manage and deal with the kernel’s modules?

The kernel’s modules are pieces of code that can be dynamically loaded and unloaded into the running kernel to add or extend functionality. Furthermore, these modules are also called kernel modules or drivers.

Now, let’s take a quick look at how modprobe command is used:

sudo modprobe [options] [module_name]

There are different options that we can pass to customize the modprobe command. Common options include -r to remove or unload a module and -v for verbose output.

Furthermore, we can load a kernel module with the modprobe command as seen here:

sudo modprobe our_module

Similarly, we can unload the kernel module with the -r option as mentioned earlier.

Furthermore, we can view information about the module with the -D option as seen here:

sudo modprobe -D our_module

Additionally, we can check if a module is currently loaded with the lsmod command. In other words, it lists all loaded modules.

Alternatively, we can use the modinfo command to display information about a module, including whether it’s currently loaded.

lsmod | grep our_module # Check if a module is loaded
modinfo our_module # Display module information


As seen above we can use the modprobe command to manage kernel modules. This comes in handy when we need to deal with hardware drivers or add functionalities to the kernel without having to reboot the system.
