Linux目录递归改变文件名大小写

experiment目录递归，indent C standard style


[root@localhost Desktop]# ls
experiment-2.6-new.tar.bz2
digui-dir-alter-case.sh
experiment
[root@localhost Desktop]# ./digui-dir-alter-case.sh experiment


digui-dir-alter-case.sh 文件内容如下：


#!/bin/sh

#晚上没事，用shell写了个递归遍历目录的脚本，本脚本实现递归遍历指定目录，打印目录下的文件名（全路径）。不为别的，就为了以后用着方便。
