Find out more information about your system

To find out more information about your Linux system, you can use the uname (stands for unix name) command. This command prints the hostname, kernel version, the CPU information, and other useful information about the computer and the Linux operating system running on it.

Used without any options, the uname command simply prints the OS name:

To print the device hostname, use the -n option:
