History of everything you copy paste (clipboard)

[@MishaLestev]

Here's the 2nd command (script):
#!/bin/bash
LOG_FILE=~/clipboard.log
while true; do
CURRENT_CLIP=$(pbpaste)
if [[ "$CURRENT_CLIP" != "$LAST_CLIP" ]]; then
echo "$(date): $CURRENT_CLIP" >> "$LOG_FILE"
LAST_CLIP="$CURRENT_CLIP"
fi
sleep 1
done
