       updatedb - update a file name database

       updatedb [options]

       This  manual  page documents the GNU version of updatedb, which updates
       file name databases used by GNU locate.	The file name  databases  con‐
       tain  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 filesys‐
       tem.  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(1).  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 different byte orderings to share
       the databases.  The new GNU locate can read both the old and new	 data‐
       base  formats.  However, old versions of locate and find produce incor‐
       rect results if given a new-format database.

       --findoptions='-option1 -option2...'
	      Global options to pass on to  find.   The	 environment  variable
	      FINDOPTIONS also sets this value.	 Default is none.

       --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 data‐
	      base.  The environment variable NETPATHS also sets  this	value.
	      Default is none.

       --prunepaths='path1 path2...'
	      Directories  to  not  put in the database, which would otherwise
	      be.  Remove any trailing slashes from the path names,  otherwise
	      updatedb	won´t recognise the paths you want to omit (because it
	      uses them as  regular  expression	 patterns).   The  environment
	      variable	PRUNEPATHS  also  sets	this  value.   Default is /tmp
	      /usr/tmp /var/tmp /afs.

	      File systems to not put in the database, which  would  otherwise
	      be.   Note  that files are pruned when a file system is reached;
	      any file system mounted under an undesired file system  will  be
	      ignored.	The environment variable PRUNEFS also sets this value.
	      Default is nfs NFS proc.

	      The database file to build.  Default  is	system-dependent.   In
	      Debian GNU/Linux, the default is /var/cache/locate/locatedb.

	      The  user	 to  search  non-network  directories as, using su(1).
	      Default is to search the non-network directories as the  current
	      user.   You  can	also use the environment variable LOCALUSER to
	      set this user.

	      The user to search network directories as, using su(1).  Default
	      is daemon.  You can also use the environment variable NETUSER to
	      set this user.

	      Create the database in the old format.  This is  a  synonym  for

	      Create  the  database in format F.  The default format is called
	      LOCATE02.	 F can be old to select the old database format	 (this
	      is the same as specifying --old-format).	Alternatively the slo‐
	      cate format is also supported.  When the slocate	format	is  in
	      use, the database produced is marked as having security level 1.
	      If you want to build a system-wide  slocate  database,  you  may
	      want to run updatedb as root.

	      Print the version number of updatedb and exit.

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

       find(1),	 locate(1),  locatedb(5),  xargs(1)  Finding Files (on-line in
       Info, or printed)

       The updatedb program correctly handles filenames	 containing  newlines,
       but  only if the system's sort command has a working -z option.	If you
       suspect that locate may need to return filenames	 containing  newlines,
       consider using its --null option.

       The  best  way  to  report  a  bug  is to use the form at http://savan‐
       nah.gnu.org/bugs/?group=findutils.  The reason for  this	 is  that  you
       will then be able to track progress in fixing the problem.   Other com‐
       ments about updatedb(1) and about the findutils package in general  can
       be  sent	 to  the  bug-findutils	 mailing list.	To join the list, send
       email to bug-findutils-request@gnu.org.
