DMESG: Displays the kernel boot information

The DMESG command is used to print boot information for Linux systems, and kernel stores the boot information in ring buffer. You can use DMESG to view (print or control the kernel ring buffer) If you are too late to view the information. The boot information is also stored in the/VAR/LOG/DMESG file. Some hardware devices (such as seventh signaling cards, voice cards, and so on) are usually installed with drivers (kernel modules), and some information is printed, which can be viewed through the DMESG command.

Because the DMESG command outputs a bit more, it is usually used in conjunction with commands such as Less/more/tail/grep.
