保留包含时间戳日志脚本

今天登陆主机发现磁盘空间不足，看了下是tomcat的catalina.out日志较多，查看logging.properties如下：

]$ tail logging.properties

# To see debug messages for HTTP/2 handling, uncomment the following line:
#org.apache.coyote.http2.level = FINE

# To see debug messages for WebSocket handling, uncomment the following line:
#org.apache.tomcat.websocket.level = FINE
1catalina.org.apache.juli.AsyncFileHandler.maxDays = 3
2localhost.org.apache.juli.AsyncFileHandler.maxDays = 3
3manager.org.apache.juli.AsyncFileHandler.maxDays = 3
4host-manager.org.apache.juli.AsyncFileHandler.maxDays = 3

貌似没生效，也没查到为啥不生效。。。

写个简单脚本应付下吧（必须要有时间戳才行，时间戳中间有字符的就拼接下）。

$ chown op1: .keep3days.sh
$ chmod +x .keep3days.sh
$ ll -a

保留4天日志脚本如下：

$ cat .keep3days.sh
#!/bin/bash
home=/export/package/front-tomcat
time1=$(date "+%Y%m%d")
j=$(expr $time1 - 3)

#echo $j
for i in `ls $home/logs | grep out | awk -F '-' '{print $2}'`
do
        #echo $i
        if [ $j -ge $i ];then
                rm -f $home/logs/catalina.out-$i
        fi
done
