Read manual page for system command.

+ -M Override $MANPATH
- Man pages are divided into 8 sections, each with an info page (man 8 info).
- 1) executables, 2) syscalls, 3) library functions, 4) /dev files,
- 5) file formats (ala /etc/hosts), 6) games, 7) miscelanous, 8) sysadmin
+ Man pages are divided into 8 sections:
+ 1 commands 2 system calls 3 library functions 4 /dev files
+ 5 file formats 6 games 7 miscellaneous 8 system management
- If you don't specify a section it'll show the lowest numbered one,
- but "man 1 mkdir" and "man 2 mkdir" are different things.
-
- The shell builtins don't have section 1 man pages, see the "help" command.
+ Sections are searched in the order 1 8 3 2 5 4 6 7 unless you specify a
+ section. Each section has a page called "intro", and there's a global
+ introduction under "man-pages".
