Sopi

Sopi (Sort Pictures) is a simple Julia program written by Fabrice that takes a list of files from our camera (with extension "JPG") and move them in a directory tree named after the date, also appending the hour of the shot to the filename itself.

This replaces the script SortTime which we were using until then but that was taking too much time to be convenient (over a second per file). Testing on 563 files from our last batch of pictures, it reduced the 17min37s of SortTime to 1min9s, which is more reasonable!

Usage

Install sopi in a binary directory (e.g., /usr/bin) as an executable; It relies on exiftool which can be installed with sudo apt install libimage-exiftool-perl.

Run on the destination directory:

sopi /home/laussy/pics/

Sopi won't run if not given a directory. To work in the current directory:

sopi .

To work on various directories, put them in a file dirs.txt and call

cat dirs.txt | xargs -I '{}' sopi {}

History

• v0°1 on 10 October (2020). Simplest features.
• v0°11 on 1 November (2020). Numbered-months (01-January, etc.), pretty-labelling of dates & fix a bug for May.
• v0°2 on 1 January (2021). Standalone version (no need to copy the script) processing working directory as an argument.
• v0°3 on 5 January (2024). Fixed a bug for some images with invalid timestamps.

Todo

There should be an option to add the timestamp to the image itself which can be done by hand by uncommenting the following:

#    mv(lfn[i],dest[1]*lmonths[:,2][parse(Int64,dest[2])]*dest[3]*"/"*replace(replace(lfn[i],".JPG"=>"-"),".jpg"=>"-")*alltimes[i,2]*".jpg")

This is not needed for photos that come from the phone, which are already tagged, but is necessary for those of the camera.
