man - print out the manual
man [ - ] [ -a ] [ -M path ] [ section ] title ...
Man is the program which provides on-line access to the UNIX manual. If a section speci-
fier is given, man looks in that section of the manual for the given title(s). Section is
either an Arabic section number (``3'' for example), or one of the words ``local'',
``new,'' or ``old''. (The abbreviations ``l'', ``n'', and ``o'' are also allowed.) If
section is omitted, man searches all sections of the manual, giving preference to commands
over library subroutines, and displays the first manual page it finds, if any. If the -a
option is supplied, man displays all applicable manual pages.
Normally man checks in standard locations (/usr/man and /usr/local/man) for manual infor-
mation. This can be changed by supplying a search path (a la the Bourne shell) with the
-M flag. The search path is a colon (``:'') separated list of directories in which man
expects to find the standard manual subdirectories. This search path can also be set with
the environmental variable MANPATH.
Since some manual pages are intended for use only on certain machines, man only searches
those directories applicable to the current machine. Man's determination of the current
machine type can be overridden by setting the environmental variable MACHINE.
If the standard output is a teletype, and the - flag is not provided, man uses more(1) , or
the pager provided by the environmental variable PAGER, to display the manual page.
The FORTRAN version of section 3 of the manual may be specified by supplying man with the
section ``3f''. Also, a specific section of the local manual may be specified by append-
ing a number to the section, i.e. ``l5'' would indicate section 5 of the local manual.

The manual is supposed to be reproducible either on the phototypesetter or on a type-
writer, however, on a typewriter, some information is necessarily lost.
