Users can also simply type g.rename -help without arguments on the command line, to receive a menu of existing data base element types and files from which to choose for possible renaming:
rast rast file(s) to be renamed oldvect oldvect file(s) to be renamed (GRASS 5.0) vect vect file(s) to be renamed (GRASS >5.1) icon icon file(s) to be renamed labels labels file(s) to be renamed sites sites file(s) to be renamed region region file(s) to be renamed group group file(s) to be renamed 3dview 3dview file(s) to be renamed
If the user attempts to rename a file to itself by setting the new file name equal to the old file name (e.g., g.rename rast=soils,soils), g.rename will not execute the rename, but instead state that no rename is needed. However, g.rename will allow the user to overwrite other existing files in the current mapset by making the new file name that of an already existing file.
For portability reasons, g.rename is ignoring case of names. To change the case of a map name, first rename the map to a name which differs by more than case, then rename it to the intended name.
# rename raster map g.rename rast=oldrast,newrast # rename vector map g.rename vect=oldvect,newvect # combined renaming g.rename rast=oldrast,newrast vect=oldvect,newvect
