定期删除日志脚本

日志存储特别浪费资源，直接写脚本定期删。
话不多说，直接上代码；

[root@localhost hua]# pwd
/home/user_1/hua

cleanNacosLog.sh内容如下：
记得赋权： chmod +x cleanNacosLog.sh

#!/bin/bash
currTime=$(date +"%Y-%m-%d %T")
cd /home/user_1/ke/nacos/bin/logs
outpath=/home/user_1/hua
echo $currTime " 清理日志脚本执行开始 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>">> ${outpath}/catalina.out
del_date=`date +%Y-%m-%d -d "5 days ago"`
for n in `ls *.log -1`;do
    m=`echo $n | awk -F. '{print $(NF-1)}'`
    m=`echo ${m:0-10}`
    if [ ! $m ]; then
        continue
    fi
    if [[ $m < $del_date || $m = $del_date ]];then 
        echo "file" $n "will be deleted." >> ${outpath}/catalina.out
        rm -rf $n
    fi
done
echo $currTime" 清理日志脚本执行结束 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>">> ${outpath}/catalina.out
echo "       ">> ${outpath}/catalina.out

[root@localhost hua]# cat catalina.out
