Class Grep

java.lang.Object
  gnu.regexp.util.Grep

public class Grep
extends Object

Grep is a pure-Java clone of the GNU grep utility. As such, it is much slower and not as full-featured, but it has the advantage of being available on any system with a Java virtual machine.

grep

public static int grep(String[] argv,
                       gnu.regexp.RESyntax syntax,
                       PrintStream out)

Runs Grep with the specified arguments. For a list of supported options, specify "--help". This is the meat of the grep routine, but unlike main(), you can specify your own syntax and PrintStream to use for output.
