Notes:

1. You don't need to use etc/run for running normal commands.

2. The GRASS "bin" directory will be prepended to the path when you
start GRASS, so you don't need to specify it explicitly.

So, it would be sufficient to write:

g.remove rast=MASK
g.copy rast=mask_grid,MASK
g.region n=${bound_4} s=${bound_3} e=${bound_2} w=${bound_1} nsres=${nsres} ewres=${ewres}
