man and info pages

So I was reading the chmod-manpage ;-) and what did it say? "The full documentation for chmod is maintained as a Tex info manual. If the info and chmod programs are properly installed at your site, the command info chmod should give you access to the complete manual." What surprises me again and again is: the infopages are not that complete! I got *way* more information on chmod from the manpages than from the infopages. And it's not only for chmod, *all* infopages I have read so far are small, don't give any explanation whatsoever, only list the options without explaining what they do.. Am I missing something here or is this an aspect of Linux not being completely worked on? Rogier Maas
