Which of the following Linux commands is used to read another command's documentation?
A. cat
B. sudo
C. chmod
D. man
正解:D
解説:
The correct answer is C. man, which stands for manual. The man command is used in Linux and UNIX- based operating systems to display the official documentation for commands, configuration files, and system calls. This documentation includes descriptions, syntax, available options, and usage examples.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that Linux relies heavily on built-in documentation accessible from the command line. The man pages are considered the authoritative reference for how a command works and what options it supports. For example, running man cp displays documentation for the file copy command.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that learning to use man is essential for Linux administration and troubleshooting. Unlike graphical help systems, man pages are always available locally and do not require internet access.
The Mike Meyers / Mark Soper Lab Manual clarifies that chmod changes file permissions, cat displays file contents, and sudo allows commands to be run with elevated privileges. None of these commands provide documentation about other commands.
Because the question specifically asks about reading another command's documentation, the Linux command designed for that exact purpose is man, making C the correct answer.
