Hello,
I have some problem with the use of bash scripts for the r.mapcalc function. For bash loop operation, I use the fprint function in order allow GRASS to read each steps of the loop but this doesn't work with r.mapcalc.
Did someone alredy do some loops for the r.mapcalcs function with bash scripts in GRASS?
Thank for your help.

Could you be more precise about what doesn't work ?

I've often used for loops with r.mapcalc operations, but never using printf. Why not call r.mapcalc directly, i.e.
#!/bin/bash
for i in $(seq 1 1 100)
do
r.mapcalc "new_rast = rast${i}@mapset*100"
done
?

I tried with what you proposed. It work fine.
I just did an error with the ' quote.
Thanks
Lucien
