Thanks for all the pointers on this query. I applied the method of
Eliot and managed to get the output and grids generated with the
spatial adjustment:
#!/bin/bash
ruta_elev="Q:\geophys\Potential-field datasets\Topography\topo_17.1.img"
ruta_grav="Q:\geophys\Potential-field datasets\Gravity\grav.i

Hi Eliot,
I can see the logic of the function, but not sure how it is
implemented from the section I have:
This has to do with bash and shells in general, and is not
specific to awk or to the cygwin Unix-like environment.
But what I meant was som
As a test I did a simple function to read the inputs:
#!/bin/sh
lon_min=-12
lon_max=0
lat_min=28
lat_max=39
R_d=167
R_i=20
function Test() {
echo Test function: $lon_min $lon_max $lat_min $lat_max $R_d $R_i
}
#
Test > test.txt
# test.txt -> -12 0 28 39 167 20
Still needs awk to do those

Ok, I think I have a sense of an underlying problem here.
When you do: ... | read v1 v2 ...
The read executes in an inferior process, setting variables there.
The process then exits and you have no bindings in the parent shell,
which is where you want them.
Maybe something like this would suit
Hello,
The img2grd program is a Windows code. The script is using the GMT
software that is freely available, and accessed via Cygwin; can also
work via standard windows batch files to a more restricted degree.
The Windows path definition worked fine, thanks for that
The issue seems to be getting

This response is based on your subsequent email but what if you change

Hello,
Having sorted how to access a separate drive location, I have expanded
the script to include an awk section which processes new coordinate
limits which should pass to img2grd to extract the data grids.
However, the awk scripting does not seem to generate any data - is
there something I am m
