CATMAN(8) Manual pager utils CATMAN(8)
catman - create or update the pre-formatted manual pages
catman [-d?V] [-M path] [-C file] [section] ...
catman is used to create an up to date set of pre-formatted manual
pages known as cat pages. Cat pages are generally much faster to
display than the original manual pages, but require extra storage
space. The decision to support cat pages is that of the local
administrator, who must provide suitable directories to contain
them.
The options available to catman are the manual page hierarchies
and sections to pre-format. The default hierarchies are those
specified as system hierarchies in the man-db configuration file,
and the default sections are either the colon-delimited contents
of the environment variable $MANSECT or the standard set compiled
into man if $MANSECT is undefined. Supplying catman with a set of
whitespace-delimited section names will override both of the
above.
catman makes use of the index database cache associated with each
hierarchy to determine which files need to be formatted.
-d, --debug
Print debugging information.
-M path, --manpath=path
Specify an alternate colon-delimited manual page hierarchy
search path. By default, this is all paths indicated as
system hierarchies in the man-db configuration file.
-C file, --config-file=file
Use this user configuration file rather than the default of
~/.manpath.
-?, --help
Print a help message and exit.
--usage
Print a short usage message and exit.
-V, --version
Display version information.
MANSECT
If $MANSECT is set, its value is a colon-delimited list of
sections and it is used to determine which manual sections
to search and in what order. The default is "1 n l 8 3 0 2
3type 5 4 9 6 7", unless overridden by the SECTION
directive in /usr/local/etc/man_db.conf.
MANPATH
If $MANPATH is set, its value is interpreted as the colon-
delimited manual page hierarchy search path to use.
See the SEARCH PATH section of manpath(5) for the default
behaviour and details of how this environment variable is
handled.
/usr/local/etc/man_db.conf
man-db configuration file.
/usr/man/index.(bt|db|dir|pag)
A traditional global index database cache.
/var/catman/index.(bt|db|dir|pag)
An alternate or FSSTND compliant global index database
cache.
