Example

Without starting index

Given this folder on your desktop:

original
  |_file.jpg
  |_image.png

whose absolute path is ~/Desktop/original, rename all the files in there with prefix of Renamed:

yarn batch-rename -o ~/Desktop/original -p Renamed

Results in:

original # origin folder
  |_file.jpg
  |_image.png

original_renamed # new folder, created if not already existing
  |_Renamed-001.jpg
  |_Renamed-002.png

With starting index

Using that same folder, rename all of the files with starting index of 300:

yarn batch-rename -o ~/Desktop/original -p Renamed -s 300

Results in:

original # origin folder
  |_file.jpg
  |_image.png

original_renamed # new folder, created if not already existing
  |_Renamed-300.jpg
  |_Renamed-301.png

Useful when used with --target.

With specified target folder

Target folder already exists

Given this folder structure on your desktop:

original # contains file to rename
  |_file.jpg
  |_image.png

other # will contain renamed files
  |_Prefix-301.js

Rename all of the files in original with starting index of 302, prefix of Prefix and store in the other folder:

yarn batch-rename -o ~/Desktop/original -p Prefix -t ~/Desktop/other -s 302

Results in:

original # origin folder
  |_file.jpg
  |_image.png

other # now also contains renamed files from original
  |_Prefix-301.js
  |_Prefix-302.jpg
  |_Prefix-303.png

This is useful for when you already have files in the target folder with the given prefix.

Target folder does not yet exist

Given this folder on your desktop:

original # contains file to rename
  |_file.jpg
  |_image.png

Rename all of the files in original and store in a new copy folder in the ~/Desktop/subfolder/ directory with a prefix of Copied:

yarn batch-rename -o ~/Desktop/original -p Copied -t ~/Desktop/subfolder/copy

Results in:

Desktop
  |_original # origin folder
    |_file.jpg
    |_image.png
  |_subfolder
    |_copy # created new folder that did not exist before
      |_Copied-001.js
      |_Copied-002.jpg

This is useful for when you know exactly where you want the target folder to go.
