## gnu.regexp.util
Class Grep

    java.lang.Object
      |
      +--gnu.regexp.util.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.

Method Detail

### main

    public static void main(java.lang.String[] argv)

  Invokes the grep() function below with the command line arguments and using the RESyntax.RE_SYNTAX_GREP syntax, which attempts to emulate the traditional UNIX grep syntax.

### grep

    public static int grep(java.lang.String[] argv,
                           RESyntax syntax,
                           java.io.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.
