最近买了一本书《实战linux shell 编程与服务器管理》，根据书中提示，从http://bash.ols3.net/DL/shell-98-v1.tgz下载包文件解压，脚本文件为BIG5编码，转为UTF8：
find shell-98-v1 -type d -exec mkdir -p utf8/{} \;
find shell-98-v1 -type f -exec iconv -f BIG5 -t UTF-8 {} -o utf8/{} \;
mv utf8/* shell-98-v1
rm -fr utf8
find . 得结果

如何批量将samples目录下的脚本文件往上一目录移动，并删除samples目录？ 顺便问一下，为什么书中提到的bash 4.0新增通配符**（就是两个星星）没有效？ 书中说**可对比现行目录下所有的子目录和文件（以递归方式）。

问题一 若有文件重名,只保留一个 问题二 关于通配符我只知道

在计算机（软件）技术中，通配符可用于代替字符。

通常地，星号“*”匹配0个或以上的字符，问号“?”匹配1个字符。在SQL中，通配符可用于“LIKE”表达式中，其百分号“%”匹配0个或以上的字符。

http://zh.wikipedia.org/wiki/%E9%80%9A% ... D%E7%AC%A6
若要对比目录,论坛里有推荐工具. 自己搜索一下.

**似乎是zsh的功能

移动文件另一方法： 移动文件又一方法： 是不是有点无聊了。。。

多谢了。看来我不是一般的菜。我想到的是怎么用find 的 -exec的选项，没想到用循环和管道，awk。

bash和zsh都能用**
后面的搞不定了

find ./shell-98-v1/**/samples/ -type f -exec ls {} \;

It says to go into all the subdirectories below tmp, as well as just the content of tmp.

e.g. I have the following:

$ find tmp
tmp
tmp/a
tmp/a/b
tmp/a/b/file1
tmp/b
tmp/b/c
tmp/b/c/file2

matched output:

$ echo tmp/*
tmp/a tmp/b

matched output:

$ echo tmp/**/*
tmp/a tmp/a/b tmp/a/b/file1 tmp/b tmp/b/c tmp/b/c/file2

It is a default feature of zsh, to get it to work in bash 4, you perform:

shopt globstar
