CompTIA Linux+ (XK0-005) — Question 15

Which of the following commands will display the operating system?

Answer options

• A. uname -n
• B. uname -s
• C. uname -o
• D. uname -m

Correct answer: C

Explanation

The command 'uname -o' specifically outputs the operating system name, making it the correct choice. The other options provide different information: 'uname -n' gives the network node hostname, 'uname -s' shows the kernel name, and 'uname -m' displays the machine hardware name.
