uniq

Compare adjacent points and discard any duplicates, much like the UNIX uniq command.

uniq [field1, ... fieldN] [by groupfield1, ... groupfieldN]

fieldN	One or more fields to check for changes. If all of a point's fieldN values are the same as on the previous point, the point is discarded as being a duplicate.	No; the default is all fields other than time
by	One or more fields by which to group. See Grouping fields with by.	No
