[ncl-talk] problem with HDF data.

[Geeta Geeta]

 Hi . 
I have to plot the data in HDF format using NCL. I started using NCL about a week  back and I am in learning stage. 

I happen to see the ready script available https://www.ncl.ucar.edu/Applications/Scripts/hdf4sds_6.ncl which reads HDF data. 

On my system I downloaded this script and tried to run this but when I run this, following message comes. 
bash-3.2$ ncl hdf4sds_6.ncl

bash-3.2$ ls -l *hdf*ncl*
-rw-r--r--    1 model    staff          6725 Sep 01 17:01 hdf4sds_6.ncl
bash-3.2$


The files exist in my directory. 
Can somebody tell me what's mistake???
Geeta.
