/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:
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 are:
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.
Note that only directories can be specified, and no pattern mechanism (e.g. globbing) is used.
By default, no paths are skipped.
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.
/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).
