I add 1 CCK field and want edit this for any content(500 nodes). how to edit this nodes together?
Tnx.
If you are familiar with developing modules, you can create a custom module to define an action and then use the the Views Bulk Operations module to run that action on a particular set of nodes.
If you need or want to perform the edits manually (say, if each node needed a unique value), the editablefields module might be better.
