Final answer:
The command for renaming or renumbering multiple parcels varies depending on the software, with CAD programs offering scripting options and GIS programs like ArcGIS using the Field Calculator for bulk updates.
Step-by-step explanation:
The command used to renumber or rename multiple parcels depends on the software or system you are using. In many Computer-Aided Design (CAD) programs, such as AutoCAD, there might be scripting or batch processing options available. For geographic information system (GIS) software like ArcGIS, you could use the Field Calculator to renumber or rename parcels en masse. If the context is a command line interface or a programming language, a loop combined with a renaming function might be the solution. Understanding the specific context and software is key to identifying the exact command or set of commands that would be used to carry out this task.
