[ncl-install] Extracting tar.gz file Error

[Mary Haley]

It looks like the file may not have downloaded fully, or else your system may have gunzipped the file for you.

If you type "ls", do you see a file called "ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar"?  If so, this means it was gunzipped for you, and therefore you only need to type:

> tar -xf ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar

If the "ls" shows that you do have a filed called "ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar.gz" then there may be something wrong with it.

I just downloaded this file myself (by navigating my way to the file on the www.earthsystemgrid.org website and clicking on the word "download" next to the name).

I then typed:

ls -l ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar.gz

which showed that the file is "77612720" bytes in size:

-rw-r--r--@ 1 haley  CIT\Domain Users  77612720 Jan 13 14:56 ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar.gz

I then typed:

> tar -zxf ncl_ncarg-6.1.2.Linux_Debian6.0_x86_64_nodap_gcc445.tar.gz

and it worked just fine.
