MANPATH(5)                (2021-02-08)                 MANPATH(5)

          manpath - format of the /etc/manpath.config file

          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/manpath.config will not
          override it.

          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 auto-
               matically 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 partic-
               ularly important if man 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 /usr such as /usr/man, /usr/local/man and

               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

     MANPATH(5)                (2021-02-08)                 MANPATH(5)

               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 pro-

          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 ...").

          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

     MANPATH(5)                (2021-02-08)                 MANPATH(5)

               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 format-
               ted 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.

               This flag prevents man(1) from creating cat pages auto-

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