When you edit a file in a project, the editor is started in the work area if the work area is visible to the client. If the specified file is not in a project or if the work area for the project is not visible, the editor is started with a temporary read-only copy of the file from the database.
Note: When you edit a file in a copy-based work area, the corresponding database object is not automatically updated with your changes. You must reconcile your work area regularly after you edit and save a file.
The edit command supports the "Editing a file" subcommand.
