Hi All,

Using C++, I want to process sub-folders on my home folder sequentially each with a special naming format and containing some binary files in it:

Give above folders, I will process files in 1/ at first, 2/ at second, 3/ at third, and so on.

For some n/ folder, if I realize that n/ actually does not exist in local file system, I do not want to wait for it. Hence I will keep processing (n+1)/ folder, and so on.

However, when processing some (n+m)/ folder, previously not processed n/ folder may have been created on local file system. In this case, I do not want to miss processing it, but somehow detect its creation and process it. After processing n/ folder, I want to continue from (n+m+1)/.

How can I do this in Linux ?

What kind of architecture should I use ?

Thanks.

Bash or Perl script

use find to find out what all folders are created after you start the process.

I will take a look at that.

What about newly created files ?

You will get the answer
look the man page of find

You could just store the index of the folders you originally skipped in an array and then after processing each folder, scan the array for any folders you have missed and see if they now exist. Once you have processed them, remove them from the array. Your choice of language here is up to you but as suggested above, bash and perl are prime candidates.

I would suggest looking at inotify as well. If you are using Bash or Python, implementation is easy... not so sure about C++. Anyway, it is very lightweight and you can configure it to check for files, folders, whether they are created, opened, modified, deleted, etc. It is a great tool.
