show_object
show object(1m) show object(1m) NAME
show object - Displays attribute information about the specified object entry SYNOPSIS
cdscp show object object-name [attribute-name] [with attribute-name = attribute-value] ARGUMENTS
The full name of a specific object entry. The last simple name can contain wildcard characters. The name of a particular attribute; see Description for valid attribute names. The value of a particular attribute. DESCRIPTION
The show object command displays the names and values of the attributes specified in attribute-name. You can use a combination of attributes in a single command. Use a space to separate multiple attributes. You can use a with attribute-name = attribute-value clause to limit output only to object entries whose attributes have values equal to the specified values. If you do not supply any attributes, the command displays all attributes and their values. In addition to the following attributes, any application-defined attributes that might exist will be included in the output of this command. The following is a description of object entry attributes: Specifies the class to which an object belongs. Contains the version number of the object's class. This allows applications to build in compatibility with entries created by earlier versions. Specifies the creation timestamp (CTS) of this object entry. Specifies a unique identifier for the object being referenced. Specifies the timestamp of the most recent update to an attribute of the object entry. Privilege Required You must have read permission to the object entry. If you specify a wildcard object entry name, you also need read permission to the directory that stores the object entry. NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE. EXAMPLE
The following command lists all the attributes and their values of the object entry /.:/sales/east/floor1cp. cdscp> show object /.:/sales/east/floor1cp SHOW OBJECT /.../abc.com/sales/floor1cp AT 1991-10-15-15:53:07 CDS_CTS = 1991-10-15-19:53:03.00000003/08-00-2b-1c-8f-1f CDS_UTS = 1991-10-15-19:53:03.00000006/08-00-2b-1c-8f-1f RELATED INFORMATION
Commands: add object(1m), create object(1m), delete object(1m), list object(1m), remove object(1m), set object(1m) show object(1m)
