GrADS command: query shpopts

## q shpopts

`q shpopts`

Lists the current settings for drawing and writing out shapefiles.

### Usage Notes

This command is available with GrADS version 2.0.a9 or later.

The `clear shp` command releases all user-defined shapefile attributes from memory, and resets the output filename root and shapefile type to their default values. The `reset` and `reinit` commands will do the same thing -- use `clear shp` if you do not want to reset all the other user settings.

Please see the documentation page on shapefiles for more details.

### Examples

    ga-> reinit
    ga-> q shpopts

     polygon fill color: -1
     mark type: 3
