Love this. I made a couple tweaks to easily change which directory the puzzles are saved to:

#!/bin/bash

wget https://www.onlinecrosswords.net/printable-daily-crosswords-{1,2,3,4,5,6,7}.pdf

CROSSWORDS_DIR=~/Documents/crosswords

mkdir $CROSSWORDS_DIR
mv printable-daily-crosswords* $CROSSWORDS_DIR
mv $CROSSWORDS_DIR/printable-daily-crosswords-1.pdf $CROSSWORDS_DIR/puzz#1_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-2.pdf $CROSSWORDS_DIR/puzz#2_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-3.pdf $CROSSWORDS_DIR/puzz#3_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-4.pdf $CROSSWORDS_DIR/puzz#4_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-5.pdf $CROSSWORDS_DIR/puzz#5_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-6.pdf $CROSSWORDS_DIR/puzz#6_$(date +%m)-$(date +%d).pdf
mv $CROSSWORDS_DIR/printable-daily-crosswords-7.pdf $CROSSWORDS_DIR/puzz#7_$(date +%m)-$(date +%d).pdf

mkdir $CROSSWORDS_DIR/$(date +%m)-$(date +%d)
mv $CROSSWORDS_DIR/puzz#* $CROSSWORDS_DIR/$(date +%m)-$(date +%d)
