　　对于服务器的日常�l�护来说�Q�日志清理是非常重要的事情，如果�D�留日志�q�多则严重浪费磁盘空间同时媄响服务的性能。如果用手工方式�q�行清理�Q�会��p��太多旉��Q��ƈ且很多时候难以满��_��际要求。例如：如何在每个星期六凌晨3�Ҏ(gu��)��过2G大的日志文�g�q�行切割�Q�保留最新的100M日志记录�Q?/p>

　　�|�上没有发觉能满��x��座要求的日志切割工具�Q�因此花了一些闲暇时间自己写了一个。由于要在多个��^��C��使用�Q��ؓ了方侉K��?Java 实现。本工具命名�?LogCutter�Q�主要有以下特点�Q?/p>

支持 Linux、Mac �?Windows �{�所有常见操作系�l��^�?/strong>
支持命��o行交互式�q�行
支持后台非交互式�q�行�Q�Linux/MAC 下��?daemon �q�程实现�Q�W(xu��)indows 用系�l?Service 实现�Q?/strong>
支持两种日志清理方式�Q�删除日志文件或切割日志文�g�Q?/strong>
支持�?GB18030、UTF-8、UTF-16LE、UTF-16BE �{�常用日志文件类型进行切�Ԍ��不会发生切掉半个字符的情况）
高度可配�|�（�E�序执行周期、要删除的日志文件过期时间、要切割的日志文仉��值和保留大小�{�均可配�|?/strong>

一、启动方�?br />--------------------------------------------------
1) Windows
A) 前台�q�行: > ./run.bat
B) 后台�q�行: > ./LogCutter.exe {
-install-demand (安装手动启动服务)
-install-auto (安装自动启动服务)
-start (启动服务)
-stop (停止服务)
-status (查看服务状�?
}

*** �?***
@ LogCutter.exe �?Windows �pȝ��服务的方式运行，安装好后也可以通过 Windows 服务��理器进行管�?br /> @ LogCutter.exe 依赖 JRE 1.6, 因此必须在注册表或环境变量中讄�� %JAVA_HOME%

2) Linux / Unix
A) 前台�q�行: $ ./run.sh
B) 后台�q�行: $ ./run.sh -d

*** �?***
@ 可以讄��为开机时自动后台�q�行�Q�方法如�?

$ vi /etc/rc.d/rc.local
( 加入: ${YOUR_LOGCUTTER_PATH}/run.sh -d )
--------------------------------------------------

二、配�|�文�?br />--------------------------------------------------
1) �E�序配置文�g: ./conf/config.xml
2) 日志配置文�g: ./conf/log4j.properties (默认)
--------------------------------------------------

三、环境要�?br />--------------------------------------------------
1) Java �?�? JRE 1.6 以上
2) 依赖�E�序�? dom4j、log4j、juniversalchardet
