shell脚本编写--清理日志文件

 

把一些服务的日志进行清理：主要是 tomcat日志   nginx的access日志  springboot的jar运行输出日志

主体大致是这样子

找到文件路径，日志复制一份并以时间变量命名，清空旧文件，查找过期文件删除

注意不要直接删除旧文件。进程运行，删除日志文件不会释放磁盘资源。

logs_path=$1
date_now=$(date +%Y-%m-%d)
data_savedays=$2
cp $logs_path/catalina.out $logs_path/catalina.${date_now}.out
>$logs_path/catalina.out;

 find $logs_path -mtime  $data_savedays -name "catalina.*.out" -exec rm -rf {} \;

 

自己瑞色了一下。完整脚本如下：
