Which text-mode utility can be used to get help in Linux aside from man?

The text-mode utility that can be used to obtain help in Linux, aside from the 'man' command, is 'info'. The 'info' command is specifically designed for providing detailed documentation for GNU software and is often more comprehensive than what is available through 'man' pages. While 'man' typically gives a brief overview of command usage, the 'info' utility often offers more in-depth explanations, including examples and additional options.

The 'info' system uses a formatting style that allows for navigation through different sections of the documentation, making it easier to find related information. This is particularly useful for more complex software projects that require thorough understanding, as 'info' provides structured documentation that can be browsed in a more interactive way than 'man'.

Other options, such as 'Help', 'Guide', or 'Assistant', do not refer to standard text-mode utilities available in Linux for obtaining help. While there may be help commands or GUIs available in some distributions or applications, they are not recognized as standard tools for general command-line help in the same way that 'info' and 'man' are. Thus, 'info' stands out as the correct choice for seeking help in Linux beyond the traditional 'man' command.
