What does the 'man' command do in Linux?

The 'man' command in Linux is used to display the manual pages for commands, providing users with documentation that includes descriptions, options, and usage of specific commands. By invoking 'man' followed by the name of a command, users can quickly access detailed information on how to use that command effectively, including any arguments it may accept and examples of its use. This makes it an essential tool for anyone working in a Linux environment, as it helps users understand the functionality and options of various commands without needing to refer to external documentation.

The other options pertain to different functionalities within Linux. Managing network connections involves commands and utilities designed for network configuration, creating a new user account would require administrative commands like 'useradd', and processing file commands typically involves file manipulation commands rather than accessing documentation. Therefore, while those functions are relevant in the Linux environment, they do not describe the purpose of the 'man' command.
