Udev in Linux

Hey, guys welcome back to the channel and in this video, we are going to talk about udev, well, in Linux there are a lot of things of which if don't know about, it will not affect your career or your job or anything, these things are just there, quietly doing their work, one such thing is Udev. So as I told u in my last video that in Linux, almost all of the devices can be represented as files that is present in /dev directory right, but we haven't talked about how these files are getting created. for eg, you insert a pen drive in your system and dynamically a file gets created for it in /dev, well this is what udev does. Udev is a user-space program that receives notification from the kernel when a new device is detected. Udev examines the device, creates the device file and then initializes it. This approach had a problem though but we will talk about it in the next video when we will talk about some special filesystems. The notification which udev receive from the kernel is called uevent Udev loads the attributes from the event and the parses it rules to take appropriate action. udev rules can be found /lib/udev/rules.d or /etc/udev/rule.d lib is default /etc are overrides let's look at the storage rule and try to make some sense of it, as I said, you would never need to know all this   / awshandson   https://amzn.to/2A9DVv1 https://amzn.to/3cEGVNf
