updatedb

NAME

       updatedb - update a file name database

SYNOPSIS

       updatedb [options]

DESCRIPTION

       This  manual  page  documents the GNU version of updatedb,
       which updates file name databases used by GNU locate.  The
       file  name  databases  contain lists of files that were in
       particular directory trees when the  databases  were  last
       updated.   The file name of the default database is deter-
       mined  when  locate  and  updatedb  are   configured   and
       installed.   The  frequency  with  which the databases are
       updated and the directories for which they contain entries
       depend  on how often updatedb is run, and with which argu-
       ments.

       In networked environments, it often makes sense to build a
       database  at  the  root of each filesystem, containing the
       entries for that filesystem.  updatedb  is  then  run  for
       each filesystem on the fileserver where that filesystem is
       on a local disk, to prevent thrashing the network.   Users
       can  select which databases locate searches using an envi-
       ronment variable or command line option;  see  locate(1L).
       Databases can not be concatenated together.

       The  file  name  database format changed starting with GNU
       find and locate version 4.0 to allow machines with diffent
       byte orderings to share the databases.  The new GNU locate
       can read both the old and new database formats.   However,
       old  versions of locate and find produce incorrect results
       if given a new-format database.

OPTIONS

       --localpaths='path1 path2...'
              Non-network directories to  put  in  the  database.
              Default is /.

       --netpaths='path1 path2...'
              Network (NFS, AFS, RFS, etc.) directories to put in
              the database.  Default is none.

       --prunepaths='path1 path2...'
              Directories to not put in the database, which would
              otherwise  be.   Default  is /tmp /usr/tmp /var/tmp
              /afs.

       --output=dbfile
              The database file to  build.   Default  is  system-
              dependent, but typically /usr/local/var/locatedb.

       --netuser=user
              The  user  to  search network directories as, using
              su(1).  Default is daemon.

       --old-format
              Create the database in the old  format  instead  of
              the new one.

       --version
              Print the version number of updatedb and exit.

       --help Print  a  summary  of  the  options to updatedb and
              exit.
