[gradsusr] Extracting variable description and units from control file for use in string/title

[Joe Moore]

Hello all!

I am looking for a method to extract a variable's description and units
from the control file. For example, if I plot tmp2m, is there an easy way
to extract the description of what tmp2m is from the control file so that I
can use it on the plot in a string or title? I know I can print the
available variables and other info with the 'q file' command, but to grab
the description and unit from the resulting text seems to be a complex
task. Since I know I can 'q time' to get the time info, is there a
similarly simple way to grab a variable's description/unit?

I've searched online for examples of how to do this but I can't find
anything. Maybe I'm approaching my issue in the incorrect manner? I'm
making plots of model data for a personal website on a regular basis (eg.
similar to http://www.instantweathermaps.com/ or accuwx pro, but much, much
less comprehensive). I can't use OpenDAP with my web server, so I'm using
shell scripts + grads scripts.

Thanks,
Joe
