manpath - /etc/man_db.conf ファイルの書式
説明
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 $MANPATH is already set, the information
contained within /etc/man_db.conf will not override it.

空行または # で始まる行はコメントとして扱われ、無視されます。
- MANDATORY_MANPATH manpath_element
-
Lines of this form indicate manpaths that every automatically generated
$MANPATH should contain. This will typically include /usr/man.
- MANPATH_MAP path_element manpath_element
-
Lines of this form set up $PATH to $MANPATH mappings. For each
path_element found in the user's $PATH, manpath_element will be
added to the $MANPATH.
- MANDB_MAP manpath_element [ catpath_element ]
-
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 man is a setuid program, as (when in
the system configuration file /etc/man_db.conf 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 /usr
such as /usr/man, /usr/local/man and /usr/X11R6/man.
If cat pages from a particular manpath_element are not to be stored or
are to be stored in the traditional location, catpath_element 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 Linux FSSTND the
keyword FSSTND can be used in place of an actual directory.
Unfortunately, it is necessary to specify all system man tree paths,
including alternate operating system paths such as /usr/man/sun and any
NLS locale paths such as /usr/man/de_DE.88591.
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
/usr/man/de_DE.88591 must come before /usr/man.
- DEFINE key value
-
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 grep
and tbl), and default sets of arguments to those programs.
- SECTION section ...
-
-
Lines of this form define the order in which manual sections should be
searched. If there are no SECTION directives in the configuration file,
the default is:
-
SECTION 1 n l 8 3 0 2 5 4 9 6 7
If multiple SECTION directives are given, their section lists will be
concatenated.
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 ...").
SECTIONS is accepted as an alternative name for this directive.
- MINCATWIDTH width
-
If the terminal width is less than width, cat pages will not be created
(if missing) or displayed. The default is 80.
- MAXCATWIDTH width
-
If the terminal width is greater than width, cat pages will not be
created (if missing) or displayed. The default is 80.
- CATWIDTH width
-
width を 0
以外に設定した場合、実際に使用している端末幅にかかわらず、整形済みページは常に指定された端末幅用として整形されます。この値は通常
MINCATWIDTH と MAXCATWIDTH の間に設定します。
- NOCACHE
-
このフラグを設定した場合、 man(1) は自動的に整形済みページを作成しません。

Unless the rules above are followed and observed precisely, the manual pager
utilities will not function as desired. The rules are overly complicated.
