I am needing some help with a script. I'm currently trying to select PDF file that meets a specific requirement in the file name in order to move it to a different location. 

The filename format I'm trying to select from has separated sections like the example below:
```
I_XXX_PACK_6788669_6_9358869.pdf

```
What I am trying to do is select only files that have the last section in the file name (e.g. `9358869`) and ignore all others pdf files in the directory.
 
Can it be done with Unix tools (POSIX find, sed, grep, etc.), my main issue right now is trying to only get only the one file that was 6 separated sections in its filename and ignoring all other files.


* Also is it possible to only choose the files that were created 1hr prior to system time? I have use sed on other file types to check for time, but not on a pdf file. So I am not sure if that is possible or not
