Trying to find out where all your man pages are located, have no fear this is how you can find them.
Which will tell you what directories you computer will look for man files.
you can also look in
$ grep MANPATH /etc/manpath.config
To see where you system expects the man pages to be located.
I you would like to read some man pages about man then then ‘man man’ and ‘man 5 manpath’ for more information. If there are man pages that you have but you cant get them to show up by typing “man widget” then you simply have to add them to you man path.
