[ncl-install] Problem unzipping/untarring NCL setup file

[David Book]

Mary . . .

Thanks for the suggestion about using a tilde. 

The name I gave my computer is "Book-Enigmatics." The prompt at my home 
directory reads

Book at Book-Enigmatics ~

(i.e., it displays a tilde), but the prompt after I cd to  /usr/local 
doesn't show a tilde:

Book at Book-Enigmatics /usr/local

I tried inserting the tilde in my command:

gunzip ~/cygwin/home/Book/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz

and got this response (note the duplication in the path name):

gzip: 
/home/Book/cygwin/home/Book/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz:
 No such file or directory

Likewise with

gunzip 
~/cygwin/home/Book at Book-Enigmatics/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.
tar.gz

But FWIW, when I tried

$ tar 
~/cygwin/home/Book at Enigmatics-Book/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.
tar

the response was

tar: Old option `g' requires an argument.
Try `tar --help' or `tar --usage' for more information.

I am hopelessly at sea.

I'm not sure what the issue is there, but this is a Cygwin problem and not 
an NCL problem.  It shouldn't be an issue for installing NCL.

In order to access files in your home directory you need to use "~/", and 
not "/".  If you use "/" it thinks you mean the top directory of the Cygwin 
directory tree.

Try
gunzip ~/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz

and go from there.
