37.Dt MAN.CONF 5
38.Os
39.Sh NAME
40.Nm man.conf
41.Nd configuration file for
42.Xr man 1
43.Sh DESCRIPTION
44The
45.Xr man 1 ,
46.Xr apropos 1 ,
47and
48.Xr whatis 1
49commands
50search for manual pages or their database files as specified by the
51.Nm
52file.
53Manual pages are normally expected to be preformatted (see
54.Xr nroff 1 )
55and named with a trailing ``.0''.
56.Pp
57The
58.Nm
59file contains two types of lines.
60.Pp
61The first type of line is a ``section'' line, which contains a
62section name followed by one or more directory paths.
63The directory paths may contain the normal shell globbing characters,
64including curly braces (``{}''); to escape a shell globbing character,
65precede it with a backslash (``\e'').
66Lines in this format specify that manual pages for the section
67may be found in the following directories.
68.Pp
69Section lines may contain either absolute directory paths or relative
70directory paths (but not both).  Relative directory paths are treated
71as a list of subdirectories to append to the current directory search
72path.  Section lines with absolute directory paths (starting with
73``/'') completely replace the current directory search path with their
74content.  Absolute directory paths named with a trailing slash
75character are expected to contain subdirectories of manual pages, (see
76the keyword ``_subdir'' below) instead of man pages.  These
77subdirectories are searched instead of the directory.
78.Pp
79Before searching any directory for a manual page, the
80.Xr man 1
81command always searches the subdirectory with the same name
82as the current machine type, if it exists.
83No specification of these subdirectories is necessary in the
84.Nm
85file.
86.Pp
87Section names are unrestricted except for the reserved words specified
88below; in general, you should avoid anything with a leading underscore
89(``_'') to avoid future incompatibilities.
90.Pp
91The section named ``_default'' is the list of directories that will
92be searched if no section is specified by the user.
93.Pp
94The second type of line is preceded with a ``keyword''.
95The possible keywords and their meanings are as follows:
96.Pp
97.Bl -tag -width "_version"
98.It _build
99Man file names, regardless of their format, are expected to end in
100a ``.*'' pattern, i.e. a ``.'' followed by some suffix.
101The first field of a _build line lists a suffix which indicates
102files which need to be reformatted or manipulated in some way before
103being displayed to the user.
104The suffix may contain the normal shell globbing characters (NOT
105including curly braces (``{}'')).
106The rest of the line must be a shell command line, the standard
107output of which is the manual page in a format which may be directly
108displayed to the user.
109Any occurrences of the string ``%s'' in the shell command line will
110be replaced by the name of the file which is being reformatted.
111.It _crunch
112The ``_crunch'' section is used by catman to know how to crunch cat pages
113which originally were compressed man pages: The first field lists a suffix
114which indicates what kind of compression were used to compress the man page.
115The rest of the line must be a shell command line, used to compress the
116formatted pages.
117.It _subdir
118The list (in search order) of subdirectories which will be searched in
119any directory named with a trailing slash (``/'') character.
120This list is also used when a path is specified to the
121.Xr man 1
122utility by the user, using the
123.Ev MANPATH
124environment variable or the
125.Fl M
126and
127.Fl m
128options.
129.It _suffix
130Man file names, regardless of their format are expected to end in
131a ``.*'' pattern, i.e. a ``.'' followed by some suffix.
132Each field of a _suffix line is a suffix which indicates
133files which do not need to be reformatted or manipulated
134in any way, but which may be directly displayed to the user.
135Each suffix may contain the normal shell globbing characters (NOT
136including curly braces (``{}'')).
137.It _version
138The version of the configuration file.
139.It _whatdb
140The full pathname (not just a directory path) for a database to be used
141by the
142.Xr apropos 1
143and
144.Xr whatis 1
145commands.
146The pathname may contain the normal shell globbing characters,
147including curly braces (``{}''); to escape a shell globbing character,
148precede it with a backslash (``\e'').
149.El
150.Pp
151Multiple specifications for all types of lines are cumulative and the
152entries are used in the order listed in the file; multiple entries may
153be listed per line, as well.
154.Pp
155Empty lines or lines whose first non-whitespace character is a hash
156mark (``#'') are ignored.
157.Sh FILES
158.Bl -tag -width /etc/man.conf -compact
159.It Pa /etc/man.conf
160Standard manual directory search path.
161.El
162.Sh EXAMPLES
163Given the following
164.Nm
165file:
166.Bd -literal -offset indent
167_version	BSD.2
168_subdir		cat[123]
169_suffix		.0
170_build		.[1-9]	nroff -man %s
171_build		.tbl	tbl %s | nroff -man
172_default	/usr/share/man/
173sect3		/usr/share/man/{old/,}cat3
174.Ed
175.Pp
176By default, the command
177.Dq Li man mktemp
178will search for
179``mktemp.<any_digit>'' and ``mktemp.tbl''
180in the directories
181.Dq Pa /usr/share/man/cat1 ,
182.Dq Pa /usr/share/man/cat2 ,
183and
184.Dq Pa /usr/share/man/cat3 .
185If on a machine of type ``vax'', the subdirectory ``vax'' in each
186directory would be searched as well, before the directory was
187searched.
188.Pp
189If ``mktemp.tbl'' was found first, the command
190.Dq Li tbl <manual page> | nroff -man
191would be run to build a man page for display to the user.
192.Pp
193The command
194.Dq Li man sect3 mktemp
195would search the directories
196.Dq Pa /usr/share/man/old/cat3
197and
198.Dq Pa /usr/share/man/cat3 ,
199in that order, for
200the mktemp manual page.
201If a subdirectory with the same name as the current machine type
202existed in any of them, it would be searched as well, before each
203of them were searched.
