What is the difference between modprobe and Insmod?
insmod is similar to modprobe: it can insert a module into the Linux kernel. Unlike modprobe, however, insmod does not read its modules from a set location, automatically insert them, and manage any dependencies. insmod can insert a single module from any location, and does not consider dependencies when doing so.
What does modprobe do in Linux?
Use the modprobe command to add or remove modules on Linux. The command works intelligently and adds any dependent modules automatically. The kernel uses modprobe to request modules. The modprobe command searches through the standard installed module directories to find the necessary drivers.
Where can I find kernel module dependencies?
