一个txt文件，我怎么取出指定的一段？
如，我取出如下一段。

CREATE TABLE `cdef_items` (
  `id` mediumint( unsigned NOT NULL auto_increment,
  `hash` varchar(32) NOT NULL default '',
  `cdef_id` mediumint( unsigned NOT NULL default '0',
  `sequence` mediumint( unsigned NOT NULL default '0',
  `type` tinyint(2) NOT NULL default '0',
  `value` varchar(150) NOT NULL default '',
  PRIMARY KEY  (`id`),
  KEY `cdef_id` (`cdef_id`)
)

  mysqldump出来的txt文件如下 ，

使用mysqldump选项 --no-data

rubyish

看看:

1. 
   
2. cat dumpfile | sed -n  /CREATE.*cdef_items/,/ENGINE/p | sed s'/ ENGINE.*//'
