实现自动清除日期目录shell脚本实例代码
很多时候备份通常会使用到基于日期来创建文件夹，对于这些日期文件夹下面又有很多子文件夹，对于这些日期文件整个移除，通过find结合rm或者delete显得有些力不从心。本文提供一个简单的小脚本，可以嵌入到其他脚本，也可直接调用，如下文供大家参考。
1、脚本内容
[root@SZDB ~]# more purge_datedir.sh
#!/bin/bash
# Author: Leshami
# Blog : http://blog.csdn.net/leshami
RemoveDir=/log/hotbak/physical
dt=`date +%Y%m%d -d "3 day ago"`
for subdir in `ls $RemoveDir`;
do
if [ "${subdir}" \< "${dt}" ];
then
rm -rf $RemoveDir/$subdir >/dev/null
echo "The directory $RemoveDir/$subdir has been removed."
fi
done
2、演示
[root@SZDB ~]# ls /log/hotbak/physical 20141203 20141210 20141217 20141224 20141231 20150107 20150114 20150125 tmp.sh 20141207 20141214 20141221 20141228 20150104 20150111 20150121 20150128 [root@SZDB ~]# ./purge_datedir.sh The directory /log/hotbak/physical/20141203 has been removed. The directory /log/hotbak/physical/20141207 has been removed. The directory /log/hotbak/physical/20141210 has been removed. The directory /log/hotbak/physical/20141214 has been removed. The directory /log/hotbak/physical/20141217 has been removed. The directory /log/hotbak/physical/20141221 has been removed. The directory /log/hotbak/physical/20141224 has been removed. The directory /log/hotbak/physical/20141228 has been removed. The directory /log/hotbak/physical/20141231 has been removed. The directory /log/hotbak/physical/20150104 has been removed. The directory /log/hotbak/physical/20150107 has been removed. The directory /log/hotbak/physical/20150111 has been removed. The directory /log/hotbak/physical/20150114 has been removed. The directory /log/hotbak/physical/20150121 has been removed. [root@SZDB ~]# ls /log/hotbak/physical 20150125 20150128

P70系列延期，华为新旗舰将在下月发布
3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。
而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？
根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
