This program is intended for grouping photography images by date into a hierarchy of date related folders.
If you have a folder of photographies, say
you may run
group-by-date -r photos
The program will emit a Bash script like this one:
mkdir -p 2017/2017-06/2017-06-28 && mv photos/0001.jpeg 2017/2017-06/2017-06-28 mkdir -p 2017/2017-06/2017-06-28 && mv photos/0002.jpeg 2017/2017-06/2017-06-28 mkdir -p 2017/2017-06/2017-06-28 && mv photos/0003.jpeg 2017/2017-06/2017-06-28
You can inspect the script and if you like it, you can run it:
group-by-date -r photos | bash
If you want a different command, say copying with preservation of modification time, you can call
group-by-date --command='cp -p' -r photos
Alternatively, you can run the actions immediately, that is, without a Bash script:
group-by-date --mode=move -r photos group-by-date --mode=copy -r photos
You can also change the target directory structure
You can list all options and default values using
Attention: Media for photographies is often formatted with FAT. This may yield trouble with respect to timezones.
