[ncl-install] load command not found

[Mary Haley]

Dawit,


The problem is that you are trying to execute NCL commands directly from a
UNIX terminal window.

In order to execute NCL commands, you must use a UNIX editor to create a
file with NCL commands in it, and then you run "ncl" on this file to
execute the commands.

If you have never used a UNIX editor, then I suggest that you google for
something like "what are the best MacOS editors" or "what are the best UNIX
editors".

You should also look at NCL's "editor enhancements" page, which provides
some color-coding for NCL scripts that can be *really* useful for new users:

http://www.ncl.ucar.edu/Applications/editor.shtml

Several editors listed on this page (Atom, TextWrangler, Sublime Text) are
popular on MacOS systems.  The most widely known UNIX editors that are
pretty much available on any UNIX system are "vi" or "vim". It can useful
to know basic vi and vim commands in case you end up on a system where your
favorite UNIX editor is not available.

Once you find a UNIX editor that you want to learn, and you have it
installed on your system, then you can write your first "NCL script" using
this editor.

For example, open a UNIX editor and copy-and-paste these six lines into the
editor window:

print("Hello world")
i = 10
; This is a comment statement
j = i + 20
print("i = " + i)
print("j = " + j)

Save the file as "myscript.ncl" and exit the UNIX editor.

Now, on the UNIX command line, you can "execute" these commands in your
file by typing:

ncl myscript.ncl

You should see the following output:

(0) Hello world

Since you are new to NCL, I highly recommend that you read the the NCL User
Guide. This is an extensive document, but even just reading the first few
chapters will be helpful:

Good luck,
