Raspberry Pi devices are one of the popular board used in embedded applications. We are using on in DWS-Digital Weighing Scale. During development phase we face some challenges like device memory is full and we can't create any more files on device or update the applications. In this article we will learn How To Clear System Log Files In Raspberry Pi using various methods, including manual commands, logrotate, and GUI tools like Stacer. This is required to save disk space by managing log files efficiently much needed in embedded systems where disk space is constraint. Application Background Our application is using daemon services which starts on system startup. Also our device is connected to external peripherals like barcode scanner, label
