grib_filter examples
The grib_filter processes sequentially all grib messages contained in the input files and applies the rules to each one of them. \n Input messages can be written to the output by using the "write" statement. The write statement can be parameterised so that output is sent to multiple files depending on key values used in the output file name. \n If we write a rules_file containing the only statement:\n \n
