[gradsusr] Grads Bash scripting

[Meredith Croke]

Thanks for everyones input.. Its somewhat working.  I say somewhat because it seems like grads is getting hung up, the bash script opens grads but then it just stops, I took it out of batch mode in the hopes of seeing more detail, but no luck.  I also tried it with the variables before and after the run command:

/export/grads/bin/gradsc -lc 'run /lustre-sas1/automate/RTFDDA_track.gs "${yyyy} | ${name}"'

And in my grads script I have at the very top:
pull data
YY=subwrd(data,1)
name=subwrd(data,2)
say 'heres my name and date: 'name' 'YY
'open /lustre-sata1/data/cycles/grib_output/'YY'/grads/tropfdda0/tropfdda0.ctl'

I'm not even seeing the say command. 

Thanks again for all your help.

Meredith

in case not already answered... I would think you need

echo "blah blah blah" ... (add the quotes).  I haven't tried though as I just usually do

grads -blc "run script.gs blah blah blah"

Hi Meredith,

Yeah, that should work.  What error did you get?  The only thing I see potentially wrong there is to check and make sure you have
lat=subwrd(data,3) and not Lat=subwrd(data,3) in your GrADS script.  :-)
