---------------------------要求如下：----------------------

192.168.123.154上/oradata2/cm下的所有新的文件（包括新创建的文件夹），实现以下要求

1.文件全部拷贝到192.168.123.155下的/chi/cm

2.已经拷贝成功的文件不需要再次拷贝

实现如下：

-------------------------------output.sh---------------------

#!/bin/bash

#FILE_NAME: output.sh

#Usage : output.sh

#Desc: traverse the

echo 'too few arguments'

exit

fi

function list_all()

{

cd $1

list=`ls`

for i in $list ;do

cur_path=`pwd`

echo $cur_path/$i

if [ -d $i ] ; then

list_all $i

fi

done

cd ..

}

list_all $1
