The need for this arose with following scenario.
I have stream processing engine doing some random stuff and creating a lot
of files in the process. And since I did not wrote it myself and people who
wrote it do not have clearing up mechanism for the files that accumulate
and tend to either fill Inodes or File-system.

So needed a way for clearing things up older than 30 seconds. Ofcourse I
can touch a dummy file and then sleep for 30 seconds and then use find
-newer. But that sounds like so much for so less and for that matter, one
can parse the output of stat in perl or even in bash and do the same thing.
In this case a single line command might sound like an improvement.
