Type the command, with no options and no arguments, that prints the system's currently configured host name to standard output.

LPIC-1 Exam 102-500, objective 109. Networking fundamentals easy

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.

Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

Type the answer.

Case sensitive — Linux is, and grading LS as ls would teach a falsehood.

Why

Run with no arguments, hostname prints the name the kernel currently holds, which it reads through the gethostname system call. Given an argument and run as root it sets that name instead, but only until the next reboot, since the persistent value lives in /etc/hostname and on systemd systems is managed with hostnamectl. `uname -n` reports the same kernel value in a different tool.
