Posix Parser（ Posix Parser）

Posix解析器用于解析Posix，就像传递的参数一样。 它现已弃用，并由DefaultParser取代。

例子 (Example)

CLITester.java

import org.apache.commons.cli.CommandLine;
import org.apache.commons.cli.CommandLineParser;
import org.apache.commons.cli.Options;
import org.apache.commons.cli.ParseException;
import org.apache.commons.cli.PosixParser;
public class CLITester {
   public static void main(String[] args) throws ParseException {
      //Create posix like options
      Options posixOptions = new Options();
      posixOptions.addOption("D", false, "Display");
      posixOptions.addOption("A", false, "Act");
      CommandLineParser posixParser = new PosixParser();
      CommandLine cmd = posixParser.parse(posixOptions, args);
      if( cmd.hasOption("D") ) {
         System.out.println("D option was used.");
      }
      if( cmd.hasOption("A") ) {
         System.out.println("A option was used.");
      }
   } 
}
