Modeprobe is nothibg but a tool to load dynamically your .ko(loadable module) into your Linux. With conpared to insmod, modprobe will load all the depedency modules. It is mandatory when you dnt know what and all modules are dependent.
Module charger for new plugging hardware or software.
Wi-Fi access point or USB key Wi-Fi for example.
I want to know when "apt-add-repository" becomes mandatory to run in Ubuntu machine. Usually I used following two commands many times.
$sudo apt-get update
$sudo apt-get install
What is the relation of "apt-get install" with "apt-get update" ? What exactly "sudo apt-get update" does ?
I have a png file which I want to reduce in size and dimension. Do we have any command in ubuntu/linux to achieve the same?
Thanks in advance and sorry for hiding my identity.
