Select fields — cdo_delete • rcdo

This module selects some fields from infiles and writes them to outfile. infiles is an arbitrary number of input files. All input files need to have the same structure with the same variables on different timesteps. The fields selected depends on the chosen parameters. Parameter is a comma-separated list of \"key=value\" pairs. A range of integer values can be specified by first/last[/inc]. Wildcards are supported for string values.
