Recursive Directory Watching

[Chaqua]

Is there a way to watch a directory inside a directory inside a directory and so on.

e.g

• dir1 |- dir2 |- dir3

Because currently, I am only able to watch dir1, and if smth changes in dir2 or dir3 I dont get an event. Do I just have to add a watcher to each directory myself, or is there a function for that already I missed?

From the inotify man page:

Inotify monitoring of directories is not recursive: to monitor subdirectories under a directory, additional watches must be created.

You might want to consider using Notify, which provides a convenient API for watching directories recursively, and uses inotify under the hood on Linux.
