mandb !!!mandb NAME SYNOPSIS DESCRIPTION DATABASE CACHES OPTIONS DIAGNOSTICS FILES SEE ALSO AUTHOR ---- !!NAME mandb - create or update the manual page index caches !!SYNOPSIS __mandb__ [[__-dqsuc__|__-h__|__-V__] [[''manpath''] !!DESCRIPTION __mandb__ is used to initialise or manually update __index__ database caches that are usually maintained by __man__. The caches contain information relevant to the current state of the manual page system and the information stored within them is used by the man_db utilities to enhance their speed and functionality. When creating or updating an __index__, __mandb__ will warn of bad ROFF .so requests, bogus manual page filenames and manual pages from which the __whatis__ cannot be parsed. Supplying __mandb__ with an optional colon-delimited path will override the internal system manual page hierarchy search path, determined from information found within the man_db configuration file. !!DATABASE CACHES __mandb__ can be compiled with support for any one of the following database types. Those database types that support asynchronous updates provide enhanced speed at the cost of possible corruption in the event of unusual termination. In an unusual case where this has occured, it may be necessary to rerun __mandb__ with the __-c__ option to re-create the databases from scratch. !!OPTIONS __-d, --debug__ Produce debugging information. __-q, --quiet__ Produce no warnings. __-s, --no-straycats__ Do not spend time looking for or adding information to the databases regarding stray cats. __-p, --no-purge__ Do not spend time checking for deleted manual pages and purging them from the databases. __-c, --create__ By default, __mandb__ will try to update any previously created databases. If a database does not exist, it will create it. This option forces __mandb__ to delete previous databases and re-create them from scratch, and implies __--no-purge.__ This may be necessary if a database becomes corrupt or if a new database storage scheme is introduced in the future. __-u, --user-db__ Create user databases only, even with write permissions necessary to create system databases. __-t, --test__ Perform correctness checks on manual pages in the hierarchy search path. With this option, __mandb__ will not alter existing databases. __-h, --help__ Show the usage message, then exit. __-V, --version__ Show the version, then exit. !!DIAGNOSTICS The following warning messages can be emitted during database building. __ __ An attempt to extract whatis line(s) from the given WHATIS PARSING__ section in lexgrog(1) for more information. ____ __ __ __ __ The __ __ The wildcard !!FILES ''/etc/manpath.config'' 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. ''/var/cache/man/index.(bt|db|dir|pag)'' An FHS compliant global ''index'' database cache. !!SEE ALSO man(1), lexgrog(1), manpath(5), catman(8). The __WHATIS PARSING__ section formerly in this manual page is now part of lexgrog(1). !!AUTHOR Wilf. (G.Wilford@ee.surrey.ac.uk). Fabrizio Polacco (fpolacco@debian.org).
