BASH – Picture / Video File Name Manipulation

Often there are needs to rename a picture or video to help with organizing the files on a computer or in cloud storage. The code below can help to make some organization easier.

For those that are not use to the date format used below, it is specifically chosen to make it easier to organize first by year then month then day. If someone wanted they could go down further in organizing but for my needs year, month, and day are usually good enough.

#!/bin/sh

echo "Please type in the photographer name or simply press enter/return. "
read photographer

#region JPG or DNG
if compgen -G "*.jpg" >/dev/null || compgen -G "*.dng" >/dev/null; then
    # File is a picture that should have exif data

    # This first part will rename a picture based on the date and time the picture was taken.
    # NOTE: This will only work properly if you have the original files. It usually will not work if you downloaded the pictures from social media or other sources.
    exiftool '-filename<${datetimeoriginal#;DateFmt("%Y-%m-%d_%H.%M.%S")}${subsectimeoriginal}0.%e' .

    # This part will add the image size to the file name
    exiftool '-filename<%f_$imagesize.%e' .
