实现自动清除日期目录shell脚本实例代码
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~]#morepurge_datedir.sh
#!/bin/bash
#Author:Leshami
#Blog:http://blog.csdn.net/leshami
RemoveDir=/log/hotbak/physical
dt=`date+%Y%m%d-d"3dayago"`
forsubdirin`ls$RemoveDir`;
do
if["${subdir}"\<"${dt}"];
then
rm-rf$RemoveDir/$subdir>/dev/null
echo"Thedirectory$RemoveDir/$subdirhasbeenremoved."
fi
done
2、演示
[root@SZDB~]#ls/log/hotbak/physical 2014120320141210201412172014122420141231201501072015011420150125tmp.sh 2014120720141214201412212014122820150104201501112015012120150128 [root@SZDB~]#./purge_datedir.sh Thedirectory/log/hotbak/physical/20141203hasbeenremoved.
