.Dt MAN.CONF 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm man.conf
|
|
.Nd configuration file for
|
|
.Xr man 1
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Xr man 1 ,
|
|
.Xr apropos 1 ,
|
|
.Xr whatis 1
|
|
and
|
|
.Xr makewhatis 8
|
|
commands
|
|
search for manual pages or their database files as specified by the
|
|
.Nm
|
|
file.
|
|
Manual pages are normally expected to be preformatted (see
|
|
.Xr nroff 1 )
|
|
and named with a trailing
|
|
.Dq \.0 .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
file contains two types of lines.
|
|
.Pp
|
|
The first type of line is a
|
|
.Dq section
|
|
line, which contains a
|
|
section name followed by one or more directory paths.
|
|
The directory paths may contain the normal shell globbing characters,
|
|
including curly braces
|
|
.Pq Dq {} ;
|
|
to escape a shell globbing character,
|
|
precede it with a backslash
|
|
.Pq Dq \e .
|
|
Lines in this format specify that manual pages for the section
|
|
may be found in the following directories.
|
|
.Pp
|
|
Section lines may contain either absolute directory paths or relative
|
|
directory paths (but not both).
|
|
Relative directory paths are treated
|
|
as a list of subdirectories to append to the current directory search
|
|
path.
|
|
Section lines with absolute directory paths (starting with
|
|
.Dq / )
|
|
completely replace the current directory search path with their
|
|
content.
|
|
Absolute directory paths named with a trailing slash
|
|
character are expected to contain subdirectories of manual pages, (see
|
|
the keyword
|
|
.Dq _subdir
|
|
below) instead of man pages.
|
|
These
|
|
subdirectories are searched instead of the directory.
|
|
.Pp
|
|
Before searching any directory for a manual page, the
|
|
.Xr man 1
|
|
command always searches the subdirectory with the same name
|
|
as the current machine type, if it exists.
|
|
No specification of these subdirectories is necessary in the
|
|
.Nm
|
|
file.
|
|
.Pp
|
|
Section names are unrestricted except for the reserved words specified
|
|
below; in general, you should avoid anything with a leading underscore
|
|
.Pq Dq _
|
|
to avoid future incompatibilities.
|
|
.Pp
|
|
The section named
|
|
.Dq _default
|
|
is the list of directories that will
|
|
be searched if no section is specified by the user.
|
|
.Pp
|
|
The second type of line is preceded with a
|
|
.Dq keyword .
|
|
The possible keywords and their meanings are as follows:
|
|
.Pp
|
|
.Bl -tag -width "_version"
|
|
.It _build
|
|
Man file names, regardless of their format, are expected to end in
|
|
a
|
|
.Dq \.*
|
|
pattern, i.e. a
|
|
.Dq \&\.
|
|
followed by some suffix.
|
|
The first field of a _build line lists a suffix which indicates
|
|
files which need to be reformatted or manipulated in some way before
|
|
being displayed to the user.
|
|
The suffix may contain the normal shell globbing characters (NOT
|
|
including curly braces
|
|
.Pq Dq {} ) .
|
|
The rest of the line must be a shell command line, the standard
|
|
output of which is the manual page in a format which may be directly
|
|
displayed to the user.
|
|
Any occurrences of the string
|
|
.Dq %s
|
|
in the shell command line will
|
|
be replaced by the name of the file which is being reformatted.
|
|
.It _crunch
|
|
The
|
|
.Dq _crunch
|
|
section is used by catman to know how to crunch cat pages
|
|
which originally were compressed man pages: The first field lists a suffix
|
|
which indicates what kind of compression were used to compress the man page.
|
|
The rest of the line must be a shell command line, used to compress the
|
|
formatted pages.
|
|
.It _subdir
|
|
The list (in search order) of subdirectories which will be searched in
|
|
any directory named with a trailing slash
|
|
.Pq Dq /
|
|
character.
|
|
This list is also used when a path is specified to the
|
|
.Xr man 1
|
|
utility by the user, using the
|
|
.Ev MANPATH
|
|
environment variable or the
|
|
.Fl M
|
|
and
|
|
.Fl m
|
|
options.
|
|
.It _suffix
|
|
Man file names, regardless of their format are expected to end in
|
|
a
|
|
.Dq \.*
|
|
pattern, i.e. a
|
|
.Dq \&\.
|
|
followed by some suffix.
|
|
Each field of a _suffix line is a suffix which indicates
|
|
files which do not need to be reformatted or manipulated
|
|
in any way, but which may be directly displayed to the user.
|
|
Each suffix may contain the normal shell globbing characters (NOT
|
|
including curly braces
|
|
.Pq Dq {} ) .
|
|
.It _version
|
|
The version of the configuration file.
|
|
.It _whatdb
|
|
The full pathname (not just a directory path) for a database to be used
|
|
by the
|
|
.Xr apropos 1
|
|
and
|
|
.Xr whatis 1
|
|
commands.
|
|
The pathname may contain the normal shell globbing characters,
|
|
including curly braces
|
|
.Pq Dq {} ;
|
|
to escape a shell globbing character,
|
|
precede it with a backslash
|
|
.Pq Dq \e .
|
|
.El
|
|
.Pp
|
|
Multiple specifications for all types of lines are cumulative and the
|
|
entries are used in the order listed in the file; multiple entries may
|
|
be listed per line, as well.
|
|
.Pp
|
|
Empty lines or lines whose first non-whitespace character is a hash
|
|
mark
|
|
.Pq Dq #
|
|
are ignored.
|
|
.Sh FILES
|
|
.Bl -tag -width /etc/man.conf -compact
|
|
.It Pa /etc/man.conf
|
|
Standard manual directory search path.
|
|
.El
|
|
.Sh EXAMPLES
|
|
Given the following
|
|
.Nm
|
|
file:
|
|
.Bd -literal -offset indent
|
|
_version BSD.2
|
|
_subdir cat[123]
|
|
_suffix .0
|
|
_build .[1-9] nroff -man %s
|
|
_build .tbl tbl %s | nroff -man
|
|
_default /usr/share/man/
|
|
sect3 /usr/share/man/{old/,}cat3
|
|
.Ed
|
|
.Pp
|
|
By default, the command
|
|
.Dq Li man mktemp
|
|
will search for
|
|
.Dq mktemp.\*[Lt]any_digit\*[Gt]
|
|
and
|
|
.Dq mktemp.tbl
|
|
in the directories
|
|
.Dq Pa /usr/share/man/cat1 ,
|
|
.Dq Pa /usr/share/man/cat2 ,
|
|
and
|
|
.Dq Pa /usr/share/man/cat3 .
|
|
If on a machine of type
|
|
.Dq vax ,
|
|
the subdirectory
|
|
.Dq vax
|
|
in each
|
|
directory would be searched as well, before the directory was
|
|
searched.
|
|
.Pp
|
|
If
|
|
.Dq mktemp.tbl
|
|
was found first, the command
|
|
.Dq Li tbl \*[Lt]manual page\*[Gt] | nroff -man
|
|
would be run to build a man page for display to the user.
|
|
.Pp
|
|
The command
|
|
.Dq Li man sect3 mktemp
|
|
would search the directories
|
|
.Dq Pa /usr/share/man/old/cat3
|
|
and
|
|
.Dq Pa /usr/share/man/cat3 ,
|
|
in that order, for
|
|
the mktemp manual page.
|
|
If a subdirectory with the same name as the current machine type
|
|
existed in any of them, it would be searched as well, before each
|
|
of them were searched.
