shell腳本編寫--清理日志文件

 

把一些服務的日志進行清理：主要是 tomcat日志   nginx的access日志  springboot的jar運行輸出日志

主體大致是這樣子

找到文件路徑，日志復制一份並以時間變量命名，清空舊文件，查找過期文件刪除

注意不要直接刪除舊文件。進程運行，刪除日志文件不會釋放磁盤資源。

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。完整腳本如下：
