sift files into folders by year (or year and month)

sift-documents.sh

#!/bin/bash

## this script moves all files (not folders) in ~/Documents into folder called ~/Documents/[year]
## where [year] is the year the file was created

# Find files with extensions and move them into appropriate year folders
find ~/Documents -maxdepth 1 ! -name ".*" -name "*.*" | while IFS= read -r file; do
    # Extract the year from the file's creation timestamp
    year=$(stat -f "%Sm" -t "%Y" "$file")

    # Create the year folder if it doesn't exist
    mkdir -p "$HOME/Documents/$year"

    # Move the file into the year folder
    mv "$file" "$HOME/Documents/$year/"

    echo "Moved file: $file to $HOME/Documents/$year/"
done

sift-downloads.sh

#!/bin/bash

# Find files with extensions and move them into appropriate year-month folders
find ~/Downloads -maxdepth 1 ! -name ".*" -name "*.*" | while IFS= read -r file; do
    # Extract the year and month from the file's modification timestamp
    year=$(stat -f "%Sm" -t "%Y" "$file")
    month=$(stat -f "%Sm" -t "%m" "$file")

    # Create the year-month folder if it doesn't exist
    mkdir -p "$HOME/Downloads/$year-$month"

    # Move the file into the year-month folder
    mv "$file" "$HOME/Downloads/$year-$month/"

    echo "Moved file: $file to $HOME/Downloads/$year-$month/"
done
