g.mremove applies regular expressions and wildcards to g.remove.
If the -f force flag is not given then nothing is removed, instead
a functional g.remove command string is printed to stdout
as a preview of the action to be taken.
EXAMPLE
Delete all raster maps starting with "tmp_" in the current mapset:
# show matching raster maps but do not delete yet (as verification)
g.mremove rast="tmp_*"
# actually delete the matching raster maps
g.mremove -f rast="tmp_*"
