updatedb(1L)

     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
          determined 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
          arguments.

          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 environment
          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.
