Linux Essentials (010-160) — Question 13

Most commands on Linux can display information on their usage. How can this information typically be displayed?

Answer options

• A. By running the command with the option /? or /??.
• B. By running the command with the option ?! or ?=!.
• C. By running the command with the option /doc or /documentation.
• D. By running the command with the option -h or --help.
• E. By running the command with the option -m or --manpage.

Correct answer: D

Explanation

The correct answer, D, is accurate as the -h or --help options are commonly used in Linux to display command usage information. Options A, B, and C are incorrect because they do not correspond to standard Linux command practices. Option E, while related to usage information, refers specifically to the man command, which is not a direct method for displaying usage for all commands.
