I did "man copy_to_user" - It shows some kernel help text. It belongs to section 9. Now I would like to know ,whether is there way to display all function belongs to this section 9.
whatis -s 9 -w "*" will list the name and descriptions of all the manpages it knows about (uses the mandb database) in section 9. Be sure to quote the * character.
whatis -s 9 -w "*"
[laks@space ~]$ whatis --version whatis from man-1.6f [laks@space ~]$ whatis -s 9 -w "*" whatis: -s: unknown option
