.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility displays the manual pages named on the command line.
|
||||
Its options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Fl a
|
||||
Display all of the man pages for a specified
|
||||
.Ar section
|
||||
and
|
||||
.Ar name
|
||||
combination.
|
||||
(Normally, only the first man page found is displayed.)
|
||||
.It Fl C
|
||||
Use the specified
|
||||
.Ar file
|
||||
instead of the default configuration file.
|
||||
This permits users to configure their own man environment.
|
||||
See
|
||||
.Xr man.conf 5
|
||||
for a description of the contents of this file.
|
||||
.It Fl c
|
||||
Copy the man page to the standard output instead of using
|
||||
.Xr more 1
|
||||
to paginate it.
|
||||
This is done by default if the standard output is not a terminal device.
|
||||
.It Fl h
|
||||
Display only the
|
||||
.Dq Tn SYNOPSIS
|
||||
lines of the requested man pages.
|
||||
For commands, this is typically the command line usage information.
|
||||
For library functions, this usually contains the required include
|
||||
files and function prototypes.
|
||||
.It Fl k
|
||||
Display the header lines for any man pages matching
|
||||
.Ar keyword Ns Pq s ,
|
||||
in the same manner as
|
||||
.Xr apropos 1 .
|
||||
.It Fl M
|
||||
Override the list of standard directories which
|
||||
.Nm
|
||||
searches for man pages.
|
||||
The supplied
|
||||
.Ar path
|
||||
must be a colon
|
||||
.Pq Dq \&:
|
||||
separated list of directories.
|
||||
This search path may also be set using the environment variable
|
||||
.Ev MANPATH .
|
||||
The subdirectories to be searched, and their search order,
|
||||
is specified by the
|
||||
.Dq _subdir
|
||||
line in the
|
||||
.Nm
|
||||
configuration file.
|
||||
.It Fl m
|
||||
Augment the list of standard directories which
|
||||
.Nm
|
||||
searches for man pages.
|
||||
The supplied
|
||||
.Ar path
|
||||
must be a colon
|
||||
.Pq Dq \&:
|
||||
separated list of directories.
|
||||
These directories will be searched before the standard directories or
|
||||
the directories specified using the
|
||||
.Fl M
|
||||
option or the
|
||||
.Ev MANPATH
|
||||
environment variable.
|
||||
The subdirectories to be searched, and their search order,
|
||||
is specified by the
|
||||
.Dq _subdir
|
||||
line in the
|
||||
.Nm
|
||||
configuration file.
|
||||
.It Fl s
|
||||
Restrict the directories that
|
||||
.Nm
|
||||
will search to the specified section.
|
||||
The
|
||||
.Nm
|
||||
configuration file (see
|
||||
.Xr man.conf 5 )
|
||||
specifies the possible
|
||||
.Ar section
|
||||
values that are currently available.
|
||||
.It Fl S
|
||||
Display only man pages that have the specified string in the directory
|
||||
part of their filenames.
|
||||
This allows the man page search process criteria to be
|
||||
narrowed without having to change the MANPATH or
|
||||
.Dq _default
|
||||
variables.
|
||||
.It Fl w
|
||||
List the pathnames of the man pages which
|
||||
.Nm
|
||||
would display for the specified
|
||||
.Ar section
|
||||
and
|
||||
.Ar name
|
||||
combination.
|
||||
.El
|
||||
.Pp
|
||||
If the
|
||||
.Ql Fl s
|
||||
option is not specified,
|
||||
there is more than one argument,
|
||||
the
|
||||
.Ql Fl k
|
||||
option is not used, and the first argument is a valid section, then that
|
||||
argument will be used as if specified by the
|
||||
.Ql Fl s
|
||||
option.
|
||||
.Sh ENVIRONMENT
|
||||
.Bl -tag -width MANPATHX
|
||||
.It Ev MACHINE
|
||||
As some man pages are intended only for specific architectures,
|
||||
.Nm
|
||||
searches any subdirectories,
|
||||
with the same name as the current architecture,
|
||||
in every directory which it searches.
|
||||
Machine specific areas are checked before general areas.
|
||||
The current machine type may be overridden by setting the environment
|
||||
variable
|
||||
.Ev MACHINE
|
||||
to the name of a specific architecture.
|
||||
.It Ev MANPATH
|
||||
The standard search path used by
|
||||
.Nm
|
||||
may be overridden by specifying a path in the
|
||||
.Ev MANPATH
|
||||
environment
|
||||
variable.
|
||||
The format of the path is a colon
|
||||
.Pq Dq \&:
|
||||
separated list of directories.
|
||||
The subdirectories to be searched as well as their search order
|
||||
is specified by the
|
||||
.Dq _subdir
|
||||
line in the
|
||||
.Nm
|
||||
configuration file.
|
||||
.It Ev PAGER
|
||||
The pagination command used for writing the output.
|
||||
If the
|
||||
.Ev PAGER
|
||||
environment variable is null or not set, the standard pagination program
|
||||
.Xr more 1
|
||||
will be used.
|
||||
.El
|
||||
.Sh FILES
|
||||

|

|
||||
set in
|

||||
.\"and is expected to conform to

.\".St -p1003.2-?? .
|
||||
.Sh BUGS
|
||||
The on-line man pages are, by necessity, forgiving toward stupid
|
||||
display devices, causing a few man pages to be not as nicely formatted
|
||||
as their typeset counterparts.

|

.Os
|
||||
.Sh NAME
|
||||
.Nm man.conf
|
||||
.Nd configuration file for manual pages
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
file contains the default configuration used by
|
||||
.Xr man 1 ,
|
||||
.Xr apropos 1 ,
|
||||
.Xr whatis 1 ,
|
||||
.Xr catman 8 ,
|
||||
and
|
||||
.Xr makewhatis 8
|
||||
to find manual pages and information about manual pages (e.g. the
|
||||
whatis database).
|
||||
.Pp
|
||||
Manual pages are located by searching an ordered set of directories
|
||||
called the
|
||||
.Dq man path
|
||||
for a file that matches the name of the requested page.
|
||||
Each directory in the search path usually has a set of subdirectories
|
||||
in it (though this is not required).
|
||||
When subdirectories are used, there are normally two subdirectories
|
||||
for each section of the manual.
|
||||
One subdirectory contains formatted copies of that section's manual
|
||||
pages that can be directly displayed to a terminal, while the other
|
||||
section subdirectory contains unformatted copies of the pages (see
|
||||
.Xr nroff 1
|
||||
and
|
||||
.Xr mdoc 7 ) .
|
||||
Formatted manual pages are normally named with a trailing
|
||||
.Dq \.0
|
||||
suffix.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
file contains comment and configuration lines.
|
||||
Comment lines start with the
|
||||
.Dq #
|
||||
character.
|
||||
Blank lines are also treated as comment lines.
|
||||
Configuration lines consist of a configuration keyword followed by a
|
||||
configuration string.
|
||||
There are two types of configuration keywords: control keywords and
|
||||
section keywords.
|
||||
Control keywords must start with the
|
||||
.Dq _
|
||||
character.
|
||||
The following control keywords are currently defined:
|
||||
.Bl -tag -width "_version"
|
||||
.It _build
|
||||
identifies the set of suffixes used for manual pages that must be
|
||||
formatted for display and the command that should be used to format
|
||||
them.
|
||||
Manual 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 contains a man page suffix specification.
|
||||
The suffix specification may contain the normal shell globbing characters
|
||||
(NOT including curly braces
|
||||
.Pq Dq {} ) .
|
||||
The rest of the _build line is a shell command line whose standard
|
||||
output is a formatted manual page that can 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 formatted.
|
||||
.It _crunch
|
||||
used by
|
||||
.Xr catman 8
|
||||
to determine how to crunch formatted 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 _default
|
||||
contains the system-wide default man path used to search for man pages.
|
||||
.It _subdir
|
||||
contains the list (in search order) of section subdirectories which will
|
||||
be searched in any man path directory named with a trailing slash
|
||||
.Pq Dq /
|
||||
character.
|
||||
This list is also used, even if there is no trailing slash character,
|
||||
when a path is specified to the
|
||||
.Xr man 1
|
||||
utility by the user, by the
|
||||
.Ev MANPATH
|
||||
environment variable, or by the
|
||||
.Fl M
|
||||
and
|
||||
.Fl m
|
||||
options.
|
||||
.It _suffix
|
||||
identifies the set of suffixes used for formatted man pages
|
||||
(the
|
||||
.Dq \.0
|
||||
suffix is normally used here).
|
||||
Formatted man pages can be directly displayed to the user.
|
||||
Each suffix may contain the normal shell globbing characters (NOT
|
||||
including curly braces
|
||||
.Pq Dq {} ) .
|
||||
.It _version
|
||||
contains the version of the configuration file.
|
||||
.It _whatdb
|
||||
defines 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
|
||||
Section configuration lines in
|
||||
.Nm
|
||||
consist of a section keyword naming the section and a configuration
|
||||
string that defines the directory or subdirectory path that the section's
|
||||
manual pages are located in.
|
||||
The path 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 .
|
||||
Section keywords must not start with the
|
||||
.Dq _
|
||||
character.
|
||||
.Pp
|
||||
A section path may contain either a list of absolute directories or
|
||||
a list of or relative directories (but not both).
|
||||
Relative directory paths are treated as a list of subdirectories that
|
||||
are appended to the current man path directory being searched.
|
||||
Section configuration lines with absolute directory paths (starting with
|
||||
.Dq / )
|
||||
completely replace the current man search path directory with their
|
||||
content.
|
||||
.Pp
|
||||
Section configuration lines with absolute directory paths ending
|
||||
with a trailing slash character are expected to contain subdirectories
|
||||
of manual pages, (see the keyword
|
||||
.Dq _subdir
|
||||
above).
|
||||
The
|
||||
.Dq _subdir
|
||||
subdirectory list is not applied to absolute section directories
|
||||
if there is no trailing slash.
|
||||
.Pp
|
||||
In addition to the above rules, the
|
||||
.Xr man 1
|
||||
command also always checks in each directory that it searches for
|
||||
a subdirectory with the same name as the current machine type.
|
||||
If the machine-specific directory is found, it is also searched.
|
||||
This allows the manual to contain machine-specific man pages.
|
||||
Note that the machine subdirectory does not need to be specified
|
||||
in the
|
||||
.Nm
|
||||
file.
|
||||
.Pp
|
||||
Multiple specifications for all types of
|
||||
.Nm
|
||||
configuration lines are
|
||||
cumulative and the entries are used in the order listed in the file;
|
||||
multiple entries may be listed per line, as well.
|
||||
.Sh FILES
|
||||
.Bl -tag -width /etc/man.conf -compact
|
||||
.It Pa /etc/man.conf
|
||||
Standard manual configuration file.
|
||||
.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.
