Hi Again,
Here is JUnit file that demonstrates how to use the '-f filename'
style functionality. I'm putting these in
http://wiki.apache.org/commons/CLI2

public class CLIDemoWithOneOptionAndAnArgumentTest extends TestCase {
public void testOptionAndArgument() throws Exception {
CommandLine cmd = parseArgs(new String[]{"-l", "hell"});
assertNotNull(cmd);
Option longOption = cmd.getOption("-l");
Object widthOption = cmd.getValue("width");
assertNotNull(longOption);
assertNotNull(widthOption);
assertEquals(2, cmd.getOptions().size());
assertEquals("hell", widthOption.toString().trim());
assertEquals("[-l (--length)]", longOption.toString().trim());
}

assertNotNull(longOption);
assertEquals("[-l (--length)]", longOption.toString().trim());
}
public void testWithOneArgument() throws Exception {

assertNotNull(cmd);
assertEquals(1, cmd.getOptions().size());
Option widthOption = cmd.getOption("width");
assertNotNull(widthOption);
assertEquals("hell", widthOption.toString().trim());
}
private CommandLine parseArgs(String[] args) {
DefaultOptionBuilder optionBuilder = new DefaultOptionBuilder();

Argument widthOption = argumentBuilder
.withMinimum(0)
.withMaximum(1)

Parser parser = new Parser();
parser.setGroup(group);
CommandLine cmdLine = null;
try {
cmdLine = parser.parse(args);
} catch (OptionException e) {
System.out.println(e.getMessage());

return cmdLine;
}
}
