Class LineReduce

java.lang.Object
  util.LineReduce

public class LineReduce
extends Object

A class to reduce the number of lines in an ascii-file. This is useful if you have data-files with a huge amount of lines and only little changes. Then you can use this class, provide the file name of the data file and a drop rate on the command line and see your dispensable data vanish. The drop rate defines the number of data lines that are ignored. A drop rate of nine means that only each 10th line is dumped to standard out.
