NAME

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

DESCRIPTION

       /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  char-
       acter 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 are:

       PRUNEFS
	      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.

       PRUNENAMES
	      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.

       PRUNEPATHS
	      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 locate(1).

	      By default, no paths are skipped.

       PRUNE_BIND_MOUNTS
	      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.  As an exception,  bind  mounts  of  a
	      directory on itself are not skipped.

	      By default, bind mounts are not skipped.

NOTES

       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 updatedb(8).

NAME

       mlocate.db - a mlocate database

DESCRIPTION

       A  mlocate  database  starts  with  a file header: 8 bytes for a magic number ("mlocate" like a C literal), 4 bytes for the configuration
       block size in big endian, 1 byte for file format version (0), 1 byte for the "require visibility" flag (0 or 1), 2  bytes  padding,  and  a
       NUL-terminated path name of the root of the database.

       The  header  is	followed  by a configuration block, included to ensure databases are not reused if some configuration changes could affect
       their contents.	The size of the configuration block in bytes is stored in the file header.  The configuration block is a sequence of vari-
       able  assignments,  ordered  by	variable name.	Each variable assignment consists of a NUL-terminated variable name and an ordered list of
       NUL-terminated values.  The value list is terminated by one more NUL character.	The ordering used is defined by the strcmp () function.

       Currently defined variables are:

       prune_bind_mounts
	      A single entry, the value of PRUNE_BIND_MOUNTS; one of the strings 0 or 1.

       prunefs
	      The value of PRUNEFS, each entry is converted to uppercase.

       prunepaths
	      The value of PRUNEPATHS.

       The rest of the file until EOF describes directories and their contents.  Each directory starts with a header: 8 bytes for  directory  time
       (seconds)  in  big endian, 4 bytes for directory time (nanoseconds) in big endian (0 if unknown, less than 1,000,000,000), 4 bytes padding,
       and a NUL-terminated path name of the the directory.  Directory contents, a sequence of file entries sorted by name, follow.

       Directory time is the maximum of st_ctime and st_mtime of the directory.  updatedb(8) uses the original data if the directory time  in  the
       database  and  in the file system match exactly.  Directory time equal to 0 always causes rescanning of the directory: this is necessary to
       handle directories which were being updated while building the database.

       Each file entry starts with a single byte, marking its type:

       0      A non-directory file.  Followed by a NUL-terminated file (not path) name.

       1      A subdirectory.  Followed by a NUL-terminated file (not path) name.

       2      Marks the end of the current directory.

       locate(1) only reports file entries, directory names are not reported because they are reported as an entry in their parent directory.  The
       only exception is the root directory of the database, which is stored in the file header.
