If you do not supply a target object at the command prompt, the target object  is obtained from standard input (stdin). Stdin data can be accepted from the  keyboard, a redirected file, or as piped output from another command. To mark  the end of stdin data from the keyboard or in a redirected file, use  Control+Z, for End of File (EOF).    A quota specification determines the maximum number of directory objects a  given security principal can own in a specific directory partition.    When none of the optional parameters is specified, the distinguished name of  the directory partition object is displayed.    When -topobjowner is specified, it overrides any other specified parameters,  so that only the results of -topobjowner are displayed.    Use the dsget command to view properties of a specific object in the  directory. To search for all objects that match a specific criterion, see  Dsquery *.    As a result of dsquery searches, you can pipe returned objects to dsget and  obtain object properties. See Examples.    If a value that you supply contains spaces, use quotation marks around the  text (for example, "CN=Mike Danseglio,CN=Users,DC=Microsoft,DC=Com").    If you supply multiple values for a parameter, use spaces to separate the  values (for example, a list of distinguished names).
