运行环境：centos6.5 eclipse

可以借鉴转码译文分析

public static void insert(){

       String pathshell="/home/wjx/spider/baidu/java.sh";
       //String cmd="sort /home/wjx/spider/baidu/SearchUrl_CSDN.txt | uniq >/home/wjx/spider/baidu/SearchUrl_CSDN_b.txt;sort /home/wjx/spider/baidu/SearchUrl_OSchina.txt | uniq >/home/wjx/spider/baidu/SearchUrl_OSchina_b.txt";
       Process ps;
       try {
       //ps = Runtime.getRuntime().exec(new String[]{"sh","-c",cmd});
       ps = Runtime.getRuntime().exec(pathshell);
       ps.waitFor();
       String path = "/home/wjx/spider/baidu/";
       File f = new File(path);
       String[] names = f.list(new FilenameFilter() {
           public boolean accept(File dir, String name) {
               return name.indexOf(".txt") != -1;// 等于-1，表示不存在
           }
       });
       for (String str : names) {
           if (str.endsWith("_b.txt"))
               //insert_b(path + str);
           if (str.endsWith("_v.txt"))
               ;
       }} catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }

}

"/home/wjx/spider/baidu/java.sh" 中的shell脚本：

sort /home/wjx/spider/baidu/SearchUrl_CSDN.txt | uniq >/home/wjx/spider/baidu/SearchUrl_CSDN_b.txt
sort /home/wjx/spider/baidu/SearchUrl_OSchina.txt | uniq >/home/wjx/spider/baidu/SearchUrl_OSchina_b.txt
