What does the depmod command do?
depmod(Dependency Modules) command is used to generate a list of dependency description of kernel modules and its associated map files. This analyzes the kernel modules in the directory /lib/modules/kernel-release and creates a “Makefile”-like dependency file named modules.
What does modprobe stand for?
modprobe is a Linux program originally written by Rusty Russell and used to add a loadable kernel module to the Linux kernel or to remove a loadable kernel module from the kernel. It is commonly used indirectly: udev relies upon modprobe to load drivers for automatically detected hardware.
What is modprobe how it works?
modprobe uses the dependency lists and hardware maps generated by depmod to intelligently load or unload modules into the kernel. It performs the actual insertion and removal using the lower-level programs insmod and rmmod, respectively.
What does lsmod mean in Linux?
modules
The lsmod command is used to display the status of modules in the Linux kernel. It results in a list of loaded modules. lsmod is a trivial program which nicely formats the contents of the /proc/modules , showing what kernel modules are currently loaded.
How does modprobe command work 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.
What is modprobe Br_netfilter?
Since Linux kernel 3.18-rc1, you have to modprobe br_netfilter to enable bridge-netfilter. The bridge-netfilter code enables the following functionality: {Ip,Ip6,Arp}tables can filter bridged IPv4/IPv6/ARP packets, even when encapsulated in an 802.1Q VLAN or PPPoE header.
What is a .KO file?
Loadable kernel modules (. ko files) are object files that are used to extend the kernel of the Linux Distribution. They are used to provide drivers for new hardware like IoT expansion cards that have not been included in the Linux Distribution.
What does Uname mean in Linux?
unix name
uname (short for unix name) is a computer program in Unix and Unix-like computer operating systems that prints the name, version and other details about the current machine and the operating system running on it.
What does Insmod do in Linux?
The insmod command is used to insert modules into the kernel. Kernel modules are usually used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls. This command inserts the kernel object file (. ko) into the kernel.
What can I do with the depmod command?
This command allows you to override which version of a specific module will be used when more than one module sharing the same name is processed by the depmod command.
What is the meaning of override in English?

What is the name of the depmod file?
Finally, depmod outputs a file named modules.devname if modules supply special device names ( devname) that should be populated in /dev on boot (by a utility such as udev). If a version is provided, then that kernel version’s module directory is used rather than the current kernel version (as returned by uname -r ).
Which is the best definition of override C?
