[ncl-talk] Running NCL script from shell script

[Brian Thomas]

I get the same error using your script, myfile, and ncl code.

What is it you’re trying to do?  There maybe another/better way to do it.

Thank you Brian for your suggestion.

But the problem still persists even when I try
-------
cat myfile| while read mname
do
ncl myfile.ncl
done
-------

I am clueless what can go wrong here.

Regards,
Bidyut

Not certain, but I think your problem is the quotes around your variable name here:
echo "$mname"

Shouldn't have " " to make it echo out the contents of $mname

Hello All,

I am trying to run my ncl script from the following shell script:

#!/bash/bin
for i in {1..2}
do
echo $i
ncl myfile.ncl
done

Runs perfectly fine =>
[bidyut at localhost<mailto:bidyut at localhost>]$ sh test.sh<http://test.sh/>

What am I doing wrong?

FYI, Here are the associated file contents:
[bidyut at localhost<mailto:bidyut at localhost>]$ cat myfile
name1
name2

[bidyut at localhost<mailto:bidyut at localhost>]$ cat myfile.ncl
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"

begin

print("Hello")

end
