Exam XK0-005 topic 1 question 23 discussion

The correct command to display the operating system is C. uname -o. The uname command is used to print system information. It has several options that can be used to print different types of information. Here's what each option does in the context of the given question: A. uname -n: prints the hostname of the machine. B. uname -s: prints the kernel name of the machine. C. uname -o: prints the operating system of the machine. D. uname -m: prints the machine hardware name. Therefore, the correct option to display the operating system is C (uname -o).

[bryan@almalinux etc]$ uname -n almalinux [bryan@almalinux etc]$ uname -o GNU/Linux [bryan@almalinux etc]$ uname -s Linux [bryan@almalinux etc]$ uname -m x86_64

C. uname -o (OS) -s (kernel) is Linux -o (OS) is x86_64 https://www.youtube.com/watch?v=1AoKTorlEDc (2:28)

uname man page -a, --all print all information, in the following order, except omit -p and -i if unknown: -s, --kernel-name print the kernel name -n, --nodename print the network node hostname -r, --kernel-release print the kernel release -v, --kernel-version print the kernel version -m, --machine print the machine hardware name -p, --processor print the processor type or "unknown" -i, --hardware-platform print the hardware platform or "unknown" -o, --operating-system print the operating system --help display this help and exit --version output version information and exit

The option -o for the uname command does not display the operating system. Instead, it is used to display the operating system name, which is not the same as the operating system itself. The -s option is used to display the operating system name, which typically includes the name, version, and architecture. For example, if you run the command uname -s on a Linux system, it will return the following output: Linux So, in this case, the correct option for displaying the operating system would be -s, not -o.

# uname -o GNU/Linux

C is correct
