The manpages gives you help about everything in Linux, for example
man cp gives help about the cp-command, man bash about the Bash
command shell and man man about the man-system itself.
When you lists a manpage you can get help about the use of the system
by pressing the h-key. Find out how you can search for given words in the
manpage and how you can proceed to the next instance of the word.
