Manage the metadata stores used by Spotlight.

      mdutil [-pEsav] [-i on | off] volume ...

   -p  Spotlight caches indexes of some network devices locally.  This
       option requests that all local caches be flushed to the appropriate
       network device.

   -E  This flag will cause each local store for the volumes indicated to be
       erased. The stores will be rebuilt if appropriate.

   -i on | off
       Set the indexing status for the provided volumes to on or off.  Note
       that indexing can  be delayed due to low disk space or other conditions.

   -s  Display the indexing status of the listed volumes.

   -a  Apply command to all volumes.

   -v  Print verbose information when available.

To get a list of the available attributes for use in constructing queries, see mdimport(1), particularly the -X switch.


Show the indexing status of the root volume:

$ mdutil -s /

Erase and rebuild the spotlight index:

$ mdutil -E
