定时清理指定日期以前的日志文件,防止磁盘满
这里是如果/home下磁盘使用超过85%,则清除15天以前的,如果仍超过85%,则清除14天前的,直到低于85%
#!/bin/bash
clean()
{
local interval=$1
find /home/admin/apache/logs \( \( -name "*access_log" -or -name "*error_log" \) -and -ctime +$interval \) -print -type f -exec rm -rf {} \;
}
getsize()
{
local size=`df -h | grep "/home" | awk '{print $5}' | tr -d '%'`
return $size
}
