Linux中用eclipse编写一个类似ubuntu terminal的程序满足以下要求能够支持常用命令：lsls -lls -ldls pathls -l pathls -ld pathcd dirmkdir dirrmdir dirrm -rf filename or dirtouch filenamechmod filename or dircat filenametar -

要实现一个类似Ubuntu终端的程序，你可以使用Java编写一个控制台应用程序。以下是一个示例代码，满足你提供的要求：

import java.nio.file.Files;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
