    input.removeClass('placeholder');
  }
}).blur(function() {

if __name__ == '__main__' and len(sys.argv) > 5 and sys.argv[1][-3:].upper() == 'PDF':
  original = sys.argv[1]

  left     = int(sys.argv[2])
  top      = int(sys.argv[3])
  right    = int(sys.argv[4])

## grep
find . -type f -name "*.php" | xargs grep "DEF_BASE_LOG_PATH"

linux下查找某目录下所有文件包含某字符串的命令：
从文件内容查找匹配指定字符串的行：
$ grep "被查找的字符串" 文件名
从文件内容查找与正则表达式匹配的行：
$ grep –e “正则表达式” 文件名
查找时不区分大小写：
$ grep –i "被查找的字符串" 文件名
查找匹配的行数：

## add auto_increment id set primary
对于item_detail:
先用
alter table item_detail drop primary key;
删除原来的主键；
然后用：
alter table item_detail add column id int unsigned not null auto_increment primary key;
增加自增的主键id
