程序测试如下：
# python check_change.py Usage: python check_change.py update /home/wwwroot python check_change.py check /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
代码如下（check_change.py）：
#!/usr/bin/env python import os,sys,subprocess def update(path): f = open(file,'w') for root,dirs,files in os.walk(path): for name in files: line = os.path.join(root, name) (stdin,stderr) = subprocess.Popen(['md5sum',line],stdout=subprocess.PIPE).communicate() f.write(stdin) f.close() def check(path): f = open(file,'r') for line in f: check_ok = """echo '%s' | md5sum -c > /dev/null 2>&1""" % line #print check_ok if not subprocess.call(check_ok, shell = True) == 0: abnormal = line.split() print abnormal[1] f.close() def Usage(): print ''' Usage: python %s update /home/wwwroot python %s check /home/wwwroot ''' % (sys.argv[0],sys.argv[0]) sys.exit() if len(sys.argv) != 3: Usage() file = 'file.key' model = sys.argv[1] path = sys.argv[2] if os.path.exists(path) == False: print "
