[GRASS-user] could the region change between 2 commands in a single Bash script?

[Maciek Sieczka]

Hi!

I'm writing a Bash script that

1. outputs the region settings into a temp file, to create a Grass
   ASCII raster header (to be used in step 4)

2. outputs 2 rasters to xyz ascii files
   a. r.stats -1g raster1 > file1.xyz
   b. r.stats -1g raster2 > file2.xyz

3. processes them, converts the resust into a single Grass ASCII raster

4. imports it with r.in.ascii (header created based on region settings
   obtained in step 1)

2a and 2b might take some time.

The question: if I run my script in background, and then I change the
region before eg. step 2a completes, is there any danger that 2b will
be run in a different region?

I hope not, I need 2a and 2b product to be the same number of lines,
the same coordinates.
