find: Invoking updatedb

 
 8.3 Invoking 'updatedb'
 =======================
 
      updatedb [OPTION...]
 
    'updatedb' creates and updates the database of file names used by
 'locate'.  'updatedb' generates a list of files similar to the output of
 'find' and then uses utilities for optimizing the database for
 performance.  'updatedb' is often run periodically as a 'cron' job and
 configured with environment variables or command options.  Typically,
 operating systems have a shell script that "exports" configurations for
 variable definitions and uses another shell script that "sources" the
 configuration file into the environment and then executes 'updatedb' in
 the environment.
 
 '--findoptions='OPTION...''
      Global options to pass on to 'find'.  The environment variable
      'FINDOPTIONS' also sets this value.  Default is none.
 
 '--localpaths='PATH...''
      Non-network directories to put in the database.  Default is '/'.
 
 '--netpaths='PATH...''
      Network (NFS, AFS, RFS, etc.)  directories to put in the database.
      The environment variable 'NETPATHS' also sets this value.  Default
      is none.
 
 '--prunepaths='PATH...''
      Directories to omit from the database, which would otherwise be
      included.  The environment variable 'PRUNEPATHS' also sets this
      value.  Default is '/tmp /usr/tmp /var/tmp /afs'.  The paths are
      used as regular expressions (with 'find ... -regex', so you need to
      specify these paths in the same way that 'find' will encounter
      them.  This means for example that the paths must not include
      trailing slashes.
 
 '--prunefs='PATH...''
      Filesystems to omit from the database, which would otherwise be
      included.  Note that files are pruned when a filesystem is reached;
      Any filesystem mounted under an undesired filesystem will be
      ignored.  The environment variable 'PRUNEFS' also sets this value.
      Default is 'nfs NFS proc'.
 
 '--output=DBFILE'
      The database file to build.  The default is system-dependent, but
      when this document was formatted it was '/var/lib/locatedb'.
 
 '--localuser=USER'
      The user to search the non-network directories as, using 'su'.
      Default is to search the non-network directories as the current
      user.  You can also use the environment variable 'LOCALUSER' to set
      this user.
 
 '--netuser=USER'
      The user to search network directories as, using 'su'.  Default
      'user' is 'daemon'.  You can also use the environment variable
      'NETUSER' to set this user.
 
 '--old-format'
      Generate a 'locate' database in the old format, for compatibility
      with versions of 'locate' other than GNU 'locate'.  Using this
      option means that 'locate' will not be able to properly handle
      non-ASCII characters in file names (that is, file names containing
      characters which have the eighth bit set, such as many of the
      characters from the ISO-8859-1 character set).  Database
      Formats, for a detailed description of the supported database
      formats.
 
 '--dbformat=FORMAT'
      Generate the locate database in format 'FORMAT'.  Supported
      database formats include 'LOCATE02' (which is the default), 'old'
      and 'slocate'.  The 'old' format exists for compatibility with
      implementations of 'locate' on other Unix systems.  The 'slocate'
      format exists for compatibility with 'slocate'.  Database
      Formats, for a detailed description of each format.
 
 '--help'
      Print a summary of the command line usage and exit.
 '--version'
      Print the version number of 'updatedb' and exit.
