TestOut Linux Pro Practice Test 2025 – Complete Exam Prep Guide

The command that displays the manual for a specific command in Linux is "man [command]." The "man" command, short for "manual," provides the user with detailed documentation about the specified command, including its usage, options, and examples.

This command is foundational for users who need to understand how to use various commands and their associated parameters effectively. For example, running "man ls" will show the manual page for the "ls" command, which lists directory contents.

The other options serve different purposes or are not standard for accessing command documentation. The "help" command typically provides assistance for shell built-in commands but does not serve as the general manual system for all commands. The "info" command presents documentation in a different format, often more extensive than the "man" pages, but not all command documentation is available in the "info" system. Lastly, "doc [command]" is not a standard command used in Linux for displaying command manuals.
