今天看到一个shell题目，正好拿来练练手
需要在多个目录中 (如:beijing shanghai tianjin guangzhou 等等) 创建子目录（以年份命名），然后进入子目录，新建目录并以当天的日期命名。
最终的效果是这样的：

复制代码 代码如下:
china/guangdong/
china/guangdong/shenzhen/2010/1206
china/guangdong/shenzhen/2010/1207
china/guangdong/shenzhen/baoan/2010/1206
china/guangdong/shenzhen/baoan/2010/1207
china/guangdong/shenzhen/baoan/guangming/2010/1206
china/guangdong/shenzhen/baoan/guangming/2010/1207

我的实现：

#!/bin/bash
    read -p "PLEASE input country:" cou
    read -p "PLEASE input city:" city
    read -p "PLEASE input name:"  name
#echo "$cou,$city,$name"    
    date=$(date +%Y)
#echo $date
    date2=$(date +%m%d)
#    echo $date2
    if [ -d "./$cou/$city/$name/$date/$date2" ];then
        echo "the dir is exit"
    else
        mkdir -p ./$cou/$city/$name/$date/$date2
    fi

效果：
[root@localhost hbshell]# test.sh
PLEASE input country:china
PLEASE input city:hangzhou
PLEASE input name:hb

#[root@localhost hbshell]# ll china/hangzhou/hb/2011/0321/
