Today, I will talk to you about the example analysis of the uuid command in linux. Many people may not know much about it. In order to let everyone know more, Xiaobian summarized the following contents for everyone. I hope everyone can gain something according to this article.

UUID provides a unique identification string for a storage device in the system, regardless of the type of device. If you boot in the system, when you use the drive letter mount, you may not find the device and the load fails, but when you use the UUID mount, there will be no such problem.

/dev/disk/by-uuid xxx@xxx:/dev/disk/by-uuid$ ls -l lrwxrwx1 root 10 Apr 18 18:42 562B-5D33 -> ../../ sda112, this 562B-5D33 is the uuid corresponding to sda1.

The uuid viewed by blkid corresponds to bytes 0x43 ~ 0x46 of FAT table data, as follows

On my device, it is a small end mode, so uuid= 0x562 b-5d33, the uuid of each u disk is different, just like everyone gets an ID card, which is unique in the world.
