G'day Ken,

Thanks for the references. Let me try to explain the problem on which I am working.

I need to scan a set of directory and based on certain criteria I may need to perform a tar operation. Once the operation is successful I need to update some entries in DB( a SQLite DB).

Now the issue is say an user use Ctrl-C to abort the program. As it may come while DB operations going on it will result into a inconsistent state of DB (which need to be avoided). As if the program run again the flow will be decided based on the entries in DB.

So there are two ways to handle such case

1. Catch all such signals and let the program run

2. Catch such signals and handle the condition gracefully.

So I am thinking to take approach 2 for the same. So I was thinking how to achieve the same. Any example with this reference will be great help.

Hope this will help.
