一、安装

1)  从内核和目录里面查看是否支持inotify

[root@nfs01 ~]# uname -r

2.6.32-573.el6.x86_64

[root@nfs01 ~]#** ls -l /proc/sys/fs/inotify/**    -→主要查看下面有没有三个目录

总用量 0

-rw-r--r-- 1 root root 0 1月  21 13:03 max_queued_events

-rw-r--r-- 1 root root 0 1月  21 13:03 max_user_instances

-rw-r--r-- 1 root root 0 1月  21 13:03 max_user_watches

2**)检查是否有安装inotify **如果没有就安装

rpm -qa inotify-tools

没有就先安装epol源

yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

之后安装

[root@nfs01 ~]#** yum install inotify-tools -y**

二、参数讲解、

[root@nfs01 ~]# which inotifywait

/usr/bin/inotifywait

[root@nfsserver inotify-tools]# bin/inotifywait —help

r :递归查询目录

q:打印很少的信息,仅仅打印监控事件的信息  安静状态

m:始终保持事件监听状态

excluder#排除文件或者目录的时候不区分大小写

timefmt:指定时间输出的格式

d :后台运行

-e: 事件 里面有很多方法

复制代码

下面是事件参数

我曾七次鄙视自己的灵魂: 第一次,当它本可进取时,却故作谦卑; 第二次,当它空虚时,用爱欲来填充; 第三次,在困难和容易之间,它选择了容易; 第四次,它犯了错,却借由别人也会犯错来宽慰自己; 第五次,它自由软弱,却把它认为是生命的坚韧; 第六次,当它鄙夷一张丑恶的嘴脸时,却不知那正是自己面具中的一副; 第七次,它侧身于生活的污泥中虽不甘心,却又畏首畏尾。
