清理tomcat日志大的文件

先看一个命令：

[root@weblogic logs]# ls -c -1
catalina.2018-01-02.log
icatalina.2018-01-02:21-07.out
icatalina.2018-01-02:20-56.out
localhost_access_log.2018-01-02.txt
host-manager.2018-01-02.log
localhost.2018-01-02.log
manager.2018-01-02.log
catalina.out
catalina.2017-12-15.log
icatalina.2017-12-15:15-39.out
localhost_access_log.2017-12-15.txt
host-manager.2017-12-15.log
manager.2017-12-15.log
localhost.2017-12-15.log
catalina.2017-12-10.log
catalina.2017-12-06.log
localhost_access_log.2017-12-06.txt
localhost.2017-12-06.log
host-manager.2017-12-06.log
manager.2017-12-06.log

清理日志脚本：

[root@weblogic scripts]# cat clear_log_of_tomcat.sh 
#!/bin/bash
log_path="/usr/local/tomcat/logs"
size_init=102400
for log in `find ${log_path} -type f -mtime +10`;
do
    echo $log
    size=`ls -l $log|awk '{print $5}'`
    if [ $size -gt ${size_init} ];then
        echo "$log file is too large,start to clear"
        rm -f $log
    fi
done
