https://grass.osgeo.org/grass78/manuals/addons/g.rename.many.html "command not found". I want to rename a huge amount of raster maps in GRASS as I need them to mask the region where I will run r.stats on a loop of another stack. Names of the two stack need to have a common string to make the loop run correctly. Pattern are absolutely similar now, but a very small difference make me need to rename them all: raster to use as mask are: raster_species_1 whereas raster for which to run r.stats are: raster_species1 I have to change first stack, removing the "_" character, only solution seems, from my knowledge, using r.renmae.many, that I founded here https://grass.osgeo.org/grass78/manuals/addons/g.rename.many.html but my bash tells me "command not found". Any help about r.rename.many? should I install it somehow?
