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).    When none of the optional parameters is specified, the distinguished names of  the quota specification, the account to which the quota is assigned, and the  quota limit are all 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).
