A script to rename pictures and videos to the date they have been taken.
To run this script you first need to install exiftool, a command line utility to read exif tags.
It's available on Linux through many package managers and MacOS through direct download or through Homebrew:
brew install exiftool
You also need the Elixir runtime (> 0.12), see the .tool-versions file for the specific versions.
Run the renaming script as follows:
elixir renamer.exs path_with_pics/
An exif_results.txt file will be written in the current directory for debugging.
