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 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/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 /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.
 This flag prevents man(1) from creating cat pages automatically.


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