自動清除日期目錄shell指令碼

    很多時候備份通常會使用到基於日期來建立檔案夾，對於這些日期檔案夾下面又有很多子檔案夾，對於這些日期檔案整個移除，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指令碼，可以嵌入到其他指令碼，也可直接調用，如下文供大家參考。

 

1、指令碼內容

[[email protected] ~]# more purge_datedir.sh #!/bin/bash# Author: Leshami# Blog  : http://blog.csdn.net/leshamiRemoveDir=/log/hotbak/physicaldt=`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."    fidone

2、示範

[[email protected] ~]# ls /log/hotbak/physical20141203  20141210  20141217  20141224  20141231  20150107  20150114  20150125  tmp.sh20141207  20141214  20141221  20141228  20150104  20150111  20150121  20150128[[email protected] ~]# ./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.[[email protected] ~]# ls /log/hotbak/physical20150125  20150128
