Question

Quizplus · Accepted Answer

The "hostname" command is used to discover the name of a Unix or Linux machine when used in a shell. The options provided do not include "hostname," and the correct answer seems to be mistakenly omitted. Among the options given, none are used to discover the machine's name. "ls" lists directory contents, "ENV" is not a standard command for displaying the system name (environment variables are often viewed with "env" or set with "export"), "netmgr" is not a standard Unix/Linux command for this purpose, and "ps" displays information about running processes. Therefore, it appears there was an error in the question setup.
