如何在Linux中更改目录内容时自动运行脚本？

我想在新文件复制到特定目录时自动运行脚本.换句话说,Linux中是否有一种方法可以“监视”目录以进行更改,然后运行某些内容以响应更改？

解决方法

如果你很幸运能够使用基于debian的发行版,那么apt-get install会进行dnotify.其他发行版可能有类似的东西 – 寻找dnotify名称.

dnotify is a simple program based on Linux kernel 2.4.19+’s dnotify API.
dnotify can execute a specified command each time the content of a specific
directory changes. It is run from the command line and takes two arguments:
one or more directories to monitor and a command to execute whenever a
directory has changed. Options control what events to trigger on: when a file
was read in the directory,when one was created,deleted and so on.

如果您想在自己的程序中处理此问题,则dnotify也是您要使用的API.
