======================================================================================== Place uploader.sh in the folder where the sketch is present. Also place the port.py and board_info.txt files in the same folder. Make sure you have python already installed and present in the $PATH. If you don't have numpy: => then install numpy by using conda install numpy or pip install numpy If the script throws any error then make sure you the libraries install using arduino-cli [command exits] check for syntax errors as well.

=================== Any suggestion or correction is always welcome =====================

I recently learned 'Arduino-cli', 'Shell-scripting' and 'git'. This is my attempt to combine all of them and make a simple project out of it. This is very simple but can be helpful when you want to dump the same code to multiple boards. This will save the day for you. The local repository for me is : ~/Projects/auto_upload/test/
