Ruby 写的批量重命名脚本
作者：半瓶墨水 链接：http://www.2maomao.com/blog/extended-renamer-in-ruby/
有时候想批量修改文件名的时候，发现系统的重命名和ren命令都不好用，自己拿ruby写了一个：
用法： exren [-x] pattern replace
例子： （拜ruby的傻设计所赐，*和?两边得加上单引号’ ）
exren foo’*’.txt bar’*’.doc :重命名所有 以foo开头的txt文件 为 bar开头的doc文件
exren foo’?’.mp3 bar’?’.mp3 :略（?代表1个或者0个任意字符）
exren -x (test\d+)\.mp3 \\1.mp3 :正则表达式匹配，不理解的就算了
下载: exren.rb
