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
