實現自動清除日期目錄shell腳本實例代碼
很多時候備份通常會使用到基于日期來創建文件夾，對于這些日期文件夾下面又有很多子文件夾，對于這些日期文件整個移除，通過find結合rm或者delete顯得有些力不從心。本文提供一個簡單的小腳本，可以嵌入到其他腳本，也可直接調用，如下文供大家參考。
1、腳本內容
[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.
