Getting Help Using info Pages

The man page system is typical on Unix-like OSs, including Linux, but it’s also quite old and is therefore limited. A newer documentation system, known as info pages, is also available. The next few pages describe how info pages fill gaps in the man page system and how to use info pages.


Understanding the Purpose of info Pages

The basic design of man pages dates back decades, so it predates some important developments in managing information. Most notably, man pages are not hyperlinked. Although a See Also section is common in man pages, you can’t select one of these items to read the relevant man page directly; you must quit the man system and type a new man command to read the new page. This lack of hyperlinking also makes navigating through a large man page awkward. You can use text searches to locate information that you desire, but these often find the wrong text—or if you mistype a string, your search might fail completely.
