Find images, and copy or move them

gistfile1.txt

# Two scripts that do the same thing a little different, notice `mv` and `cp`. Your choice
# What will happen is that find will recursivly serach the current folder for images, read when
# the file was created, and move/copy it to a corresponding folder.

# This is from https://apple.stackexchange.com/questions/280252/recursively-search-for-images-and-move-them-to-a-date-folder

find -E . -regex '.*\.(jpg|JPG|png|PNG|jpeg|JPEG|bmp|BMP)' | while read file; do
    ts=$(stat -f '%Sm' -t '%Y-%m-%d' "$file")
    folder="/Users/username/Documents/Backup_images/$ts"
    [[ -d "$folder" ]] || echo mkdir "$folder"
    echo cp "$file" "$folder/"
done

find ./ -type f \( -iname \*.jpg -o -iname \*.png -o -iname \*.bmp -iname \*.jpeg \) | while read file; do
    ts=$(stat -f '%Sm' -t '%Y-%m-%d' "$file")
    folder="/Users/username/Documents/Backup_images/$ts"
    [[ -d "$folder" ]] || echo mkdir "$folder"
    echo mv "$file" "$folder/"
done

# Just remove the `echo` from the script, to let them do their thing

To search for files in a specific file size: find . -name "*.png" -size -160k. This searches for files under 160k, if you would like to search for files exactly 160k you will do find . -name "*.png" -size 160k, notice the lack of the - before the actual size.
