The error when run is:

ERROR 4: `///' does not exist in the file system,
and is not recognised as a supported dataset name.

          Append r if giving lower left and upper right coordinates
        -Rg or -Rd for global domain

Basically the variables lon_e_min, lon_e_max, lat_e_min and lat_e_max
are not transferred as inputs to -R.

I don't get any errors from the awk part.
