[ncl-install] Regarding setting of root path for NCL

[Kevin Hallock]

Hello,

Based on the error message you are seeing, I seems like you might be trying to run NCL commands directly in Bash (or whatever your shell environment is):
$ load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
bash: load: command not found

The ‘$’ character represents the Bash prompt.

Instead, please try running the “ncl” command in your shell environment:
$ ncl

ncl 0> load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
ncl 1> load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl”

Note that the above example is an interactive NCL session, where the prompt is indicated by “ncl #>”.

Ordinarily, those load commands should be added to an NCL script that you’re writing in order to enable certain NCL functions. You can execute an NCL script from Bash by running the “ncl” command followed by the name of the script, for example:
$ ncl myscript.ncl

Please let me know if you have any further questions.

I hope this helps,
Kevin
