Some MEL commands can
            take an edit flag that
            allows you to make changes to the attributes of an object. The edit
            flag is used in conjunction with other flags specifying which attributes
            to change.
         
         To edit objects with Maya commands
         
         
            - Select the polygonal cube
            
- Edit the height of the cube by typing
               the following in the Script Editor:
               polyCube -edit -height 3; 
This is equivalent to
                  changing attribute values within the Attribute Editor in
                  the Maya interface.
                
- Edit the radius of the sphere named test_Sphere by typing the following in
               the Script Editor:
               polySphere -edit -radius 1 test_Sphere; 
Commands can operate
                  on objects other than what is currently selected by specifying an
                  object name as an argument. The name must be the last argument in
                  the command.
                
- Select the cube and the sphere simultaneously
               by holding down shift and clicking the sphere.
            
- Delete the objects by typing the following
               in the Script Editor
               NoteA list of all flags
                     available for a specific command can be displayed in the  Script
                        Editor by typing  help
                        command;. For example,  help
                        sphere; provides a list of flags for the sphere command.
