日志
使用find命令定期删除n天前的日志文件
日志和备份多了，硬盘不够了，所以删除之
bear@njava:/data/log$ find /data/log -mtime +3 -exec rm -rf {} \;
关于find参数-mtime,-ctime,-atime
bear@njava:~$ man find
-mtime n
File's data was last modified n*24 hours ago. See the comments for -atime to understand how rounding
affects the interpretation of file modification times.
-ctime n
File's status was last changed n*24 hours ago. See the comments for -atime to understand how rounding
affects the interpretation of file status change times.
-atime n
File was last accessed n*24 hours ago. When find figures out how many 24-hour periods ago the file
was last accessed, any fractional part is ignored, so to match -atime +1, a file has to have been
accessed at least two days ago.
