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

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
