A user may access data stored under the other mapsets listed in their mapset search path. However, the user may only modify data stored under their own current mapset. g.copy allows the user to copy existing data files from other mapsets to the user’s current mapset ($MAPSET). The files to be copied must exist in the user’s current mapset search path and location; output is sent to the relevant data element directory(ies) under the user’s current mapset.


If the user wished to copy the existing raster file soils to a file called soils.ph and to copy an existing vector map roads to a file called rds.old, the user could type:

g.copy raster=soils,soils.ph
g.copy vector=roads,rds.old
# or even combined:
g.copy raster=soils,soils.ph vector=roads,rds.old

Data files can also be specified by their mapsets.  For example, the below command copies the raster map named soils from the mapset wilson to a new file called soils to be placed under the user’s current mapset:

g.copy raster=soils@wilson,soils

If no mapset name is specified, g.copy searches for the named from map in each of the mapset directories listed in the user’s current mapset search path in the order in which mapsets are listed there (see g.mapsets).
