In Linux, users can access built-in documentation and command references directly from the terminal. Below are the most common ways to get help when working with commands. 1. Using the man Command (Manual Pages) The man command provides detailed documentation for Linux commands, including syntax, options, and examples. Syntax: bash Copy Edit man command_name Example: bash Copy Edit man ls Displays the manual page for the ls command. Search for a Keyword in Manual Pages: bash Copy Edit man -k keyword Example: bash Copy Edit man -k copy This will show all manual pages related to "copy." 2. Using the --help Option Most Linux commands support the --help flag, which provides a brief summary of the command's usage and available options. Syntax: bash Copy Edit command --help Example: bash Copy Edit ls --help Displays a summary of options for the ls command.
