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。

cd ${workdir}

if [ ${workdir} = "/" ]

then

else

cur_dir=$(pwd)

for dirlist in $(ls ${cur_dir})

if test -d ${dirlist};then

cd ${dirlist}

cd ..

#在Linux系统下批量改变文件名字的大小写

then

then

exit 1

else

echo "the Directory isn't exist which you input,pls input a new one!!"
