The program tests are as follows:

    # python check_change.py        Usage:python check_change.py update/home/wwwroot               /home/wwwroot    #  python check_change.py update/data/www #生成站点的md5值    #  echo ' >/data/www/sitemap.html #测试清空文件 
        #  rm-rf/data/www/sitemap.xml #测试删除文件    #  python check_change.py Check/data/www  #查找那些文件被篡改    /data/www/sitemap.xml    /data/www/sitemap.html

The code is as follows (check_change.py):

    #!/usr/bin/env python          Importos,sys,subprocessdefUpdate (PATH): F= Open (file,'W')           forRoot,dirs,filesinchOs.walk (path): forNameinchFiles:line=Os.path.join (Root, name) (Stdin,stderr)= subprocess.
