[gradsusr] Grads Bash scripting

[Gregory Clarke]

Meredith,

Place the arguments behind your script name; i.e. 

/export/grads/bin/gradsc -blc "run gs.sf.surface.wind_mps ${yyyy} ${name}
${lat}"

then use similar commands at the top of your script as before using "args"
instead of "data":

yyyy=subwrd(args,1)
name=subwrd(args,2)
Lat=subwrd(args,3)

Thank you very much for your suggestion, this did work.  Now if I want
to pass multipe varibale(ie lat/lon, name) can I do it the same way
listing them before the export?  Ie:
echo ${yyyy} ${name} ${lat} | /export/grads/bin/gradsc -blc "run
gs.sf.surface.wind_mps"

yyyy=subwrd(data,1)
name=subwrd(data,2)
Lat=subwrd(data,3)

I am getting an error when I do it this way.

Thanks.

Meredith

Hi Meredith,

To go from bash to GrADS, try doing something like this.  In your bash
script, add a line like this....

echo ${yyyy} | /export/grads/bin/gradsc -blc "run
gs.sf.surface.wind_mps"

In your gs.sf.surface.wind_mps script, at the very top, add these
lines....

pull data
yyyy=subwrd(data,1)

Then you can reference the yyyy in the rest of the GrADS script like
this....
'draw title Testing 'yyyy' year'

Hope this helps some.
