.TH MANPATH 5 2021-02-08 2.9.4 /etc/manpath.config
.SH NAAM
manpath \- format of the /etc/manpath.config file
.SH BESCHRIJVING
The manpath configuration file is used by the manual page utilities to
assess users' manpaths at run time, to indicate which manual page
hierarchies (manpaths) are to be treated as system hierarchies and to assign
them directories to be used for storing cat files.

If the environment variable $\fBMANPATH\fP is already set, the information
contained within /etc/manpath.config will not override it.
.SH FORMAT
The following field types are currently recognised:
.TP 
\fB#\fP\fI\ comment\fP
Blank lines or those beginning with a \fB#\fP will be treated as comments and
ignored.
.TP 
\fBMANDATORY_MANPATH\fP\fI\ manpath_element\fP
Lines of this form indicate manpaths that every automatically generated
$\fBMANPATH\fP should contain.  This will typically include \fI/usr/man\fP.
.TP 
\fBMANPATH_MAP\fP\fI\ path_element\ manpath_element\fP
Lines of this form set up $\fBPATH\fP to $\fBMANPATH\fP mappings.  For each
\fIpath_element\fP found in the user's $\fBPATH\fP, \fImanpath_element\fP will be
added to the $\fBMANPATH\fP.
.TP 
\fBMANDB_MAP \fP\fImanpath_element \fP\|[\| \fIcatpath_element\fP \|]
Lines of this form indicate which manpaths are to be treated as system
manpaths, and optionally where their cat files should be stored.  This field
type is particularly important if \fBman\fP is a setuid program, as (when in
the system configuration file /etc/manpath.config rather than the per\-user
configuration file .manpath)  it indicates which manual page hierarchies to
access as the setuid user and which as the invoking user.

The system manual page hierarchies are usually those stored under \fI/usr\fP
such as \fI/usr/man\fP, \fI/usr/local/man\fP and \fI/usr/X11R6/man\fP.

If cat pages from a particular \fImanpath_element\fP are not to be stored or
are to be stored in the traditional location, \fIcatpath_element\fP may be
omitted.

Traditional cat placement would be impossible for read only mounted manual
page hierarchies and because of this it is possible to specify any valid
directory hierarchy for their storage.  To observe the \fBLinux FSSTND\fP the
keyword \fBFSSTND\fP can be used in place of an actual directory.

Unfortunately, it is necessary to specify \fBall\fP system man tree paths,
including alternate operating system paths such as \fI/usr/man/sun\fP and any
\fBNLS locale\fP paths such as \fI/usr/man/de_DE.88591\fP.

As the information is parsed line by line in the order written, it is
necessary for any manpath that is a sub\-hierarchy of another hierarchy to be
listed first, otherwise an incorrect match will be made.  An example is that
\fI/usr/man/de_DE.88591\fP must come before \fI/usr/man\fP.
.TP 
\fBDEFINE\fP\fI\ key\ value\fP
Lines of this form define miscellaneous configuration variables; see the
default configuration file for those variables used by the manual pager
utilities.  They include default paths to various programs (such as \fIgrep\fP
and \fItbl\fP), and default sets of arguments to those programs.
.TP 
\fBSECTION\fP \fIsection\fP .\|.\|.
.RS
Lines of this form define the order in which manual sections should be
searched.  If there are no \fBSECTION\fP directives in the configuration file,
the default is:
.PP
.RS
.nf
.if  !'po4a'hide' SECTION 1 n l 8 3 0 2 5 4 9 6 7
.fi
.RE
.PP
If multiple \fBSECTION\fP directives are given, their section lists will be
concatenated.
.PP
If a particular extension is not in this list (say, 1mh) it will be
displayed with the rest of the section it belongs to.  The effect of this is
that you only need to explicitly list extensions if you want to force a
particular order.  Sections with extensions should usually be adjacent to
their main section (e.g. "1 1mh 8 ...").
.PP
\fBSECTIONS\fP is accepted as an alternative name for this directive.
.RE
.TP 
\fBMINCATWIDTH\fP\fI\ width\fP
If the terminal width is less than \fIwidth\fP, cat pages will not be created
(if missing) or displayed.  The default is 80.
.TP 
\fBMAXCATWIDTH\fP\fI\ width\fP
If the terminal width is greater than \fIwidth\fP, cat pages will not be
created (if missing) or displayed.  The default is 80.
.TP 
\fBCATWIDTH\fP\fI\ width\fP
If \fIwidth\fP is non\-zero, cat pages will always be formatted for a terminal
of the given width, regardless of the width of the terminal actually being
used.  This should generally be within the range set by \fBMINCATWIDTH\fP and
\fBMAXCATWIDTH\fP.
.TP 
.if  !'po4a'hide' .B NOCACHE
This flag prevents \fBman\fP(1)  from creating cat pages automatically.
.SH BUGS
Unless the rules above are followed and observed precisely, the manual pager
utilities will not function as desired.  The rules are overly complicated.
