With the KDE or GNOME desktop, you can also access (or print) man pages and info pages:
In Konqueror, to view the man page for ls, type man:/ls in the location bar. If there are different categories for a command, Konqueror displays them as links. To display the info page for grep, for example, type info:/grep.
In the KDE help center, check out in the table of contents to browse man pages and info pages.
Run yelp man:ls or yelp info:ls to display the man or info page.
