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：
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/
