傻逼微软会给文件前面加上efbbbf， 导致开发人员浪费很多时间在排错上，下面通过python代码来实现去除微软BOM的功能

用法很简单，指定可能含有BOM开头的文件，并且将微软的\r\n 换成linux的\n ，作用不影响原文件，会生产一个副本

 

import sysif len(sys.argv) < 2 :    print "please special the filename that maybe have BOM(SB Microsoft Files)";    sys.exit(2);filename = sys.argv[1];content = open(filename, "r").read().encode("hex");if "efbbbf" in content:    print "Oh God!!, the file have stepped on the Microsoft shit";    print "Cleaning it now!!"    print "======================================================="    print content    content = content.replace("efbbbf","");    content = content.replace("0d0a","0a");open(filename+"_noBOM","w").write(content.decode('hex'));
