自动清除日期目录shell脚本
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
