Script to organize files based on their creation dates in Hazel. Can be wrapped in a for loop to target multiple files outside of Hazel.

main.sh

# $1 is the path to the file that you want to move. This is automatically set in Hazel on Mac.
# If you're not using this with Hazel, uncomment the line below and set the file's direct path.
# 1=file/path/here

# If you're using this with a different type other than pdfs, change all occurences of *.pdf in the file to *.ext,
# where .ext is the extension of the file type you are targeting.

# Variable to store directory structure.
date=`date -r "$1" +%Y/%b/%d`

# Uncomment to set parent directory to copy to:
# cd directory/to/move/to

# Make nested folder structure only if it needs to be made.
mkdir -p "$date"

# Get the number of pdfs in the folder.
count=`find ${date} -name "*.pdf" | wc -l`
count_trimmed="$(echo -e "${count}" | tr -d '[:space:]')"

# Move file to folder.
mv "$1" "${date}/${count_trimmed}.pdf"
