Is there an easy and quick way to *get* the value of an attribute
(whether global or variable) from a (bash) shell commandline or
script? AFAICS
* NCO's `ncatted` will allow one to *set* an attribute value, but is
write-only.
* R package=ncdf4 will allow one to get an attribute value, but
requires loading R, plus writing a fair bit of code.
Am I missing something? Currently, unless I need to run R for other
reasons, I'm writing bash like
if [[ "$(ncdump -h ${F} | fgrep -e ${OUTPUT_VAR_NAME}:units)" =~
"${OUTPUT_VAR_UNITS}" ]] ; then
echo -e 'output!'
fi
which is not as robust as I'd like.
