Did you try parsing the output from 'q ctlinfo' ? --Jennifer

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'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.
