Data processing with the Linux tools
Conclusion
As the examples in this article clearly demonstrate, you do not need a special program to complete some of the mundane tasks that are a part of your everyday computing life. Often a simple text file will suffice to capture data, and the tools typically available in Raspbian, along with some knowledge about how to use them, can serve to process the data as needed. You can choose a scripting language or other method according to individual preference. As with almost any Linux operating system, many roads lead you to the same destination.
