       /etc/updatedb.conf - a configuration file for updatedb(8)


       /etc/updatedb.conf  is  a  text  file.   Blank  lines are ignored.  A #
       character outside of a quoted string starts a comment  extending  until
       end of line.

       Other lines must be of the following form:
              VARIABLE = "VALUE"

       White  space  between  tokens  is ignored.  VARIABLE is an alphanumeric
       string which does not start  with  a  digit.   VALUE  can  contain  any
       character  except for ".  No escape mechanism is supported within VALUE
       and there is no way to write VALUE spanning more than one line.

       Unknown VARIABLE values are considered an error.  The defined variables

              A  whitespace-separated  list  of  file system types (as used in
              /etc/mtab) which should not be scanned by updatedb(8).  The file
              system  type  matching is case-insensitive.  By default, no file
              system types are skipped.

              When scanning a file system is skipped, all file systems mounted
              in  the  subtree  are  skipped  too, even if their type does not
              match any entry in PRUNEFS.

              A whitespace-separated list of directory names  (without  paths)
              which  should  not  be  scanned  by updatedb(8).  By default, no
              directory names are skipped.

              Note that only directories can  be  specified,  and  no  pattern
              mechanism (e.g.  globbing) is used.

              A  whitespace-separated  list of path names of directories which
              should not be scanned by updatedb(8).  Each path  name  must  be
              exactly  in the form in which the directory would be reported by

              By default, no paths are skipped.

              One of the strings 0, no, 1 or yes.  If PRUNE_BIND_MOUNTS  is  1
              or  yes,  bind  mounts are not scanned by updatedb(8).  All file
              systems mounted in the subtree of a bind mount  are  skipped  as
              well, even if they are not bind mounts.

              By default, bind mounts are not skipped.


       When  a  directory  is  matched  by  PRUNEFS, PRUNENAMES or PRUNEPATHS,
       updatedb(8) does not scan the contents of the directory.  The  path  of
       the directory itself is, however, entered in the created database.  For
       example, if /tmp is in PRUNEPATHS, locate(1) will not  show  any  files
       stored  in  /tmp,  but  it  can show the /tmp directory.  This behavior
       differs from traditional locate implementations.

       In some updatedb(8) implementations PRUNEPATHS can be used  to  exclude
       non-directory files.  This is not the case in this implementation.

       /etc/updatedb.conf  is  a  shell  script in some implementations, which
       allows much more flexibility in  defining  the  variables.   Equivalent
       functionality  can  be  achieved  by  using the command-line options to
