uniq | Choose unique data records into classes |
-d <data> | source data |
-cout <cldata> | target classification |
[-auto] | automated naming for classes |
This operation locates unique data records. It creates a class for each unique key and collects the indexes of those data records matching the key into the class. If flag -auto is given, then the new classes are named using a running index. Otherwise, created new classes are named using the names of the fields and a combination of the values in those "unique" data records.
Example: A typical use for uniq is to find unique data records according to some key fields and then summarize other descriptive fields within these unique groups.
