формат файла /usr/local/etc/man_db.conf (format of the /usr/local/etc/man_db.conf file)
Имя (Name)
manpath - format of the /usr/local/etc/man_db.conf file
Описание (Description)
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 /usr/local/etc/man_db.conf will not
override it.
Формат (Format)
The following field types are currently recognised:
# comment
Blank lines or those beginning with a # will be treated as
comments and ignored.
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 /usr/local/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
If width 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 MINCATWIDTH and
MAXCATWIDTH.
NOCACHE
This flag prevents man(1) from creating cat pages
automatically.
Ошибки (баги) (Bugs)
Unless the rules above are followed and observed precisely, the
manual pager utilities will not function as desired. The rules
are overly complicated.
