[GRASS-user] Subset several bands of data at one go

Hi all!

As you know landsat data has separate files for different bands. Creating a
subset is a wise option to work on region of our interest. Therefore, I used
this method to subset my image -
d.zoom || g.region
g.region -p
r.mapcalc *subset*=original
as suggested in

But with this I can subset one band data at a time. Is it somehow possible
to use i.group and region definition to obtain subsets of all bands?
Scripting might be an answer but I have no much idea about it.

Thanks and regards,

Chethan S.
