Bash scripts to reorganise Google Photos exports from Google Takeout

#!/bin/bash

## Works with the Google Takeout format from 2020 and earlier, in which
## items are already within directories of the form "YYYY-MM-DD", and you
## want a directory hierarchy of the form "YYYY/MM/DD".
##
## You must run this script from the directory which contains all the
## directories of the form "YYYY-MM-DD". The resulting directories of the
## form "YYYY/MM/DD" will be created in this same location.

google-photos-reorganise-2021.sh

#!/bin/bash

## Works with the Google Takeout format from 2021 and later, in which
## items are all in a single directory (no timestamp necessarily in file
## or directory names), but JSON files contain Unix timestamps, and you
## want a directory hierarchy of the form "YYYY/MM/DD".
##
## You must start with all items in a folder called `undated`, and run this
## script from its parent. A folder called `dated` will then be created with
## the "YYYY/MM/DD" hierarchy within it. This will leave all files which we
## cannot sort in the `undated` directory for you to sort yourself.
