74: for a description of the contents of this file.
75: .It Fl c
76: Copy the manual page to the standard output instead of using

78: to paginate it.
79: This is done by default if the standard output is not a terminal device.
1.30 schwarze 80: .Pp
81: When using
82: .Fl c ,
83: most terminal devices are unable to show the markup.
84: To print the output of

89: .Xr col 1
90: .Fl b
91: instead.

217: argument if provided, then continues with the
218: .Fl M
219: argument, the
220: .Ev MANPATH
221: variable, the
222: .Ic manpath
223: entries in the
224: .Xr man.conf 5
225: file, or with
226: .Pa /usr/share/man : Ns Pa /usr/X11R6/man : Ns Pa /usr/local/man
227: by default.
228: Within each of these, directories are searched in the order provided.
229: Within each directory, the search proceeds according to the following
230: list of sections: 1, 8, 6, 2, 3, 5, 7, 4, 9, 3p.
231: The first match found is shown.
1.1 schwarze 232: .Pp
1.35 schwarze 233: The
234: .Xr mandoc.db 5
235: database is used for looking up manual page entries.

260: searches any subdirectories,
261: with the same name as the current architecture,
262: in every directory which it searches.
263: Machine specific areas are checked before general areas.
264: The current machine type may be overridden by setting the environment

285: .Xr errno 2
286: values, and some other emphasized words.
287: Some terms may have defining text at more than one place.
288: In that case, the
289: .Xr less 1
290: interactive commands
291: .Ic t
292: and
293: .Ic T
294: can be used to move to the next and to the previous place providing

298: .Fl O Cm tag Ns Op = Ns Ar term
299: option documented in the
