Ok, I know how to use the getRuntime().exec command.
But, I can't seem to get this to work with a Unix Pipe???

Any ideas?

Thanks

try {
String[] kshCommand =
  {
    "/bin/ksh"
    ,"-c"
    ,"command"
    ,"command_arg1"
    ,"command_arg2"
    ,"|"
    ,"grep xyz"
  };
java.lang.Process p = java.lang.Runtime.getRuntime().exec(kshCommand);

// deal with stdout, stdin and stderr of the child process using
 p.getInputStream();
 p.getOutputStream();
 p.getErrorStream();

// Now wait for the process completion
p.waitFor();
} catch (IOException ioe) {
}
