Shell script for automated sync mounted to usb action camera to my archive. GUI progress shown through zenity (matedialog) tool. This script was written for usage with udev rules.

#!/usr/bin/bash

# This script uses too much unneeded dependencies (like python for adding some integers). Sorry for that.
# You can clean it for your cases (replace python with bc for example).

# TODO: test rsync version shoud has --info=progress2 option (v3.0.10 or more)
