Info pages

Info pages are another form of online documentation that work in a similar way to man pages, but that include a type of hyperlinking even in text mode on the console. These are particularly associated with the GNU utilities. For example, the command [email protected]:~> info Is will display the info page for the Is command in an emacs-like viewer. If you move the cursor so that it is positioned over an asterisk, and then press Enter, you will follow that link to a linked page. The info command also provides a number of keyboard shortcuts to move around in the hierarchy of pages. Some of the most commonly used are the following:

♦ Tab — Skip to the next hyperlink in the current info page

♦ p — Move to the previous node in an info page

♦ q — Quit info and return to the command prompt

♦ ? — Split the current window and display help containing a list of available info commands in the bottom half. To exit from this help window, press Ctrl+X+0.

The command:

[email protected]:~> info gives you a menu that lets you reach all the info pages on the system.

As with man pages, you may find it convenient to use Konqueror as a viewer if you are working graphically. If you just type info:/ into the location bar in Konqueror, you will get a menu of all available info pages. For example, if you type info:/du you will see the info pages for the du command (see Figure 5-4).
