okay.... this is what ...gpt wrote up and from my testing it works. it
prompts me for the prefix text, adds the date, and the sequence.
#!/usr/bin/env bash
WORK_DIR="$HOME/Pictures/Rename"
cd "$WORK_DIR" || { echo "Could not change to directory: $WORK_DIR"; exit
1; }
TODAY=$(date +%Y-%m-%d)
# Prompt the user for a prefix
read -rp "Enter prefix for filenames (default: Photos): " PREFIX
PREFIX=${PREFIX:-Photos} # use default if input is empty
shopt -s nullglob # avoid literal patterns if no files
# Find the highest existing counter for today and prefix
MAX_COUNTER=0
for EXISTING in "${PREFIX}_${TODAY} - "*.*; do
[ -e "$EXISTING" ] || continue
BASENAME=$(basename "$EXISTING")
# Extract the number after the last ' - '
COUNTER_PART="${BASENAME##* - }"
COUNTER_PART="${COUNTER_PART%.*}" # remove extension
# Only consider it if it's a number
if [[ $COUNTER_PART =~ ^[0-9]+$ ]]; then
(( COUNTER_PART > MAX_COUNTER )) && MAX_COUNTER=$COUNTER_PART
fi
done
COUNTER=$((MAX_COUNTER + 1))
# Rename files
for FILE in *.jpg *.JPG *.jpeg *.JPEG *.png *.PNG; do
[ -e "$FILE" ] || continue
EXT="${FILE##*.}"
EXT=$(echo "$EXT" | tr '[:upper:]' '[:lower:]')
NEW_NAME="${PREFIX}_${TODAY} - ${COUNTER}.${EXT}"
mv "$FILE" "$NEW_NAME"
echo "Renamed '$FILE' -> '$NEW_NAME'"
COUNTER=$((COUNTER + 1))
done
