我如何在Linux中创建一个文件监听器？ [英] How do I create a file listener in linux?

问题描述

我想创建揭开序幕Linux命令当文件在这个路径就显示了一个特定目录的监听器。例如，每当一个文件显示在如C目录：/家/我想从文件中读取文本字符串，然后揭开序幕另一个命令。我想用一个循环，但似乎效率不高。

I am trying to create a listener on a specific directory that kicks off a Linux command whenever a file shows up in this path. For example, whenever a file shows up in a directory like C:/home/ I would like to read a string of text from that file and then kick off another command. I was thinking of using a loop but that seems inefficient.

推荐答案

要收到通知的像文件的创建，打开事件，修改等考虑的 inotify的。从bash中使用它的好方法是用 inotifywait 命令 - 在这里 是它的手册页。它会阻止，直到你关心的事件发生。例如：

To get notified about events like file creation, opening, modifying etc. look into inotify. A good way to use it from bash is with the inotifywait command - here is its man page. It will block until an event you care about happens. For example:

inotifywait -e create /path/to/watch
echo "ding!"

将丁当文件或目录在该路径被创建。请参阅手册页了解更多详情。
