man

MAN(1)							      General Commands Manual							    MAN(1)

NAME

       man - print sections of this manual

SYNOPSIS

       man [ option ... ] [ chapter ] title ...

DESCRIPTION

       Man locates and prints the section of this manual named title in the specified chapter.	(In this context, the word `page' is often used as
       a synonym for `section'.)  The title is entered in lower case.  The chapter number does not need a letter suffix.  If no chapter is  speci-
       fied, the whole manual is searched for title and all occurrences of it are printed.

       Options and their meanings are:

       -t     Phototypeset the section using troff(1).

       -n     Print the section on the standard output using nroff(1).

       -k     Display the output on a Tektronix 4014 terminal using troff(1) and tc(1).

       -e     Appended or prefixed to any of the above causes the manual section to be preprocessed by neqn or eqn(1); -e alone means -te.

       -w     Print the path names of the manual sections, but do not print the sections themselves.

       (default)
	      Copy  an already formatted manual section to the terminal, or, if none is available, act as -n.  It may be necessary to use a filter
	      to adapt the output to the particular terminal's characteristics.

       Further options, e.g. to specify the kind of terminal you have, are passed on to troff(1) or nroff.  Options and  chapter  may  be  changed
       before each title.

       For example:

	      man man

       would reproduce this section, as well as any other sections named man that may exist in other chapters of the manual, e.g.  man(7).

FILES

       /usr/man/man?/*
       /usr/man/cat?/*

SEE ALSO

       nroff(1), eqn(1), tc(1), man(7)

BUGS

       The  manual is supposed to be reproducible either on a phototypesetter or on a terminal.  However, on a terminal some information is neces-
       sarily lost.
