Class Grep


  • public class Grep
    extends java.lang.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.

                               RESyntax syntax,
