Hii,
I am very much familiar with shell/bash scripting, and have done couple of automations in my office life.
Here is the approach I'll take:
1. Will create a shell script in my local environment as per your requirement.
2. once completed, you test it in your environment.
3. If looks good, proceed with payment. Else I'll work on the required changes.
I have 7+ years of rich experience on UNIX/Linux based scripting where my major work is based upon automations and this task can be done very easily and efficiently.
Let's discuss over the chat and finalize the deal, I will start working on it as soon as I get the requirement details.
Regards
Abhishek.
