I’ve searched the title of this post on google in countless variations like “where are man pages present”, “where are man pages installed”, “man pages”+directory-“how to” etc., but I never got what I wanted to see.
So here goes: man pages are installed in the directory “/usr/local/man”.
In this directory, there are several more directories called man1, man2, man3 and so on upto man8.
Quoting the manual page for man, here’s what each of them stores:
1 Executable programs or shell commands
2 System calls (functions provided by the kernel)
3 Library calls (functions within program libraries)
4 Special files (usually found in /dev)
5 File formats and conventions eg /etc/passwd
7 Miscellaneous (including macro packages and convenâ
tions), e.g. man(7), groff(7)
8 System administration commands (usually only for root)
9 Kernel routines [Non standard]
To install most of the required man pages on ubuntu, just execute this command:
sudo apt-get install manpages manpages-dev manpages-posix manpages-posix-dev
In case you want to install STL library man pages too, type
sudo apt-get install libstdc++6-4.2-doc
Now to see documentation about vector, just type
NOTE: Its not “man vector”!
That’s all folks!
