DESCRIPTION
The g.copy module creates a copy of existing raster maps, vector maps, or other elements. The copy is
always created in the current mapset. The source data can be in the current mapset, in an explicitly
specified mapset, or in a mapset which is in the current mapset search path (typically the PERMANENT
mapset).
The maps and other elements to copy are specified in pairs from,to according to their types. Although
typically only one map is copied in one module call, multiple pairs can be provided for each type and
multiple types can be provided at the same time.
Relation to mapsets
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 (g.mapset -p). The files to be copied must
exist in the user’s current mapset search path (g.mapsets -p) and project; output is sent to the relevant
data element directory(ies) under the user’s current mapset.
Behavior on error
Errors typically occur when a map or other element does not exist, from and to are the same, to element
already exists and overwriting (e.g., by --overwrite) is not enabled, or the to element has an illegal
name. When only one map or other element is requested to be copied and the copying is not possible or
fails, an error is reported.
If multiple maps or other elements are copied in one command, g.copy attempts to copy as much as possible
even when problems occur with one of the elements. In that case, copying of the element causing problems
is skipped, and g.copy proceeds with copying the remaining elements. If nothing can be copied or an
error occurred during one of the copy operations, an error message is reported after other possible copy
operations were performed.
EXAMPLES
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).
