How to Bulk Rename Files into Ordered Numbers in MacOS

Jul 2

Say you have 10,000 files with random names, and you want to rename them all into 1–10000 based on its current alphabetical order.

Step 1

Go to the parent folder of the nested folders. Press Alt + Right Click on the folder and click “Copy [folder name] as a Pathname”.

Next, open Terminal and enter the command below. Replace the highlighted path with the copied path of the parent folder, then press Enter.

cd /path/to/your/parent_folder

Copy and paste this command, then press Enter.

n=1

for f in *; do

if [ -f "$f" ]; then

ext="${f##*.}"

mv -- "$f" "$n.${ext}"

n=$((n + 1))

done

Voilà. That’s all.
