E.g: # man vim | col -b > vim_manpage
Note: Using 'col -b' will filter reverse line feeds.
Q4) When we get into the folder /usr/share/man, we would see folders such as man1, man2, man3, man4 ......man9. what are all those?
# man 5 passwd
If you want to see all man pages about a command, one after the other, use the -a to man:
# man -a passwd
This way, when you reach the end of the first man page and press SPACE again, the man page from the next section will be displayed.
