       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.

       Versions of locate prior to 4.2.31 fail to correctly handle  long  file
       names  in  the  old  databse  format,  but  the default database format
       (called LOCATE02) is not affected by this  problem.   All  versions  of
       locate  since  version  4.0  support the new LOCATE02 format.   The old
       database format also cannot correctly represent non-ASCII characters.

       --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 instead of	the  new  one.
	      Avoid  using this option as older versions of locate are suscep‐
	      tible to a buffer overrun	 when  reading	old-format  databases.
	      The  old	fatabase  format is also incapable of correctly repre‐
	      senting non-ASCII characters.

	      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)

       All  versions  of  GNU  locate prior to 4.2.31 fail to correctly handle
       long (roughly, over 1024	 bytes)	 filenames  in	old-format  databases.
       This  can  lead	to  a  heap buffer overrun and it a potential security
       issue.  Verions 4.3.0 to 4.3.6 are also affected by the bug.  Databases
       in the default LOCATE02 format are correctly handled.

       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.
