推荐答案

Inotify本身是一个内核模块，可通过来自例如一个C程序. http://www.ibm.com/developerworks/linux/library/l-ubuntu-inotify/

Inotify itself is a kernel module accesible via calls from e.g. a C program. http://www.ibm.com/developerworks/linux/library/l-ubuntu-inotify/

有一个称为inotify-tools的应用程序套件，其中包含:

There is an application suite called inotify-tools, which contains:

inotifywait-等待使用inotify更改文件

inotifywait - wait for changes to files using inotify

http://linux.die.net/man/1/inotifywait

和

inotifywatch-使用inotify收集文件系统访问统计信息

inotifywatch - gather filesystem access statistics using inotify

http://linux.die.net/man/1/inotifywatch

您可以直接在命令行中使用inotify，例如像这样持续监视主目录下的所有更改(可能会产生很多输出):

You can use inotify directly from command line, e.g. like this to continuously monitor for all changes under home directory (may generate lots of output):

inotifywait -r -m $HOME

这是一个脚本，可以连续监视并响应Apache日志活动，该脚本是从inotifywait的man文件中复制的:

And here is a script that monitors continuously and reacts to Apache log activity, copied from the man file of inotifywait:

#!/bin/sh
while inotifywait -e modify /var/log/messages; do
  if tail -n1 /var/log/messages | grep httpd; then
    kdialog --msgbox "Apache needs love!"
  fi
done
