photo-renamer

Overview

This tool allows you to bulk rename image files (including RAW ones) using their EXIF info, to a format containing the timestamp. For photographers aficionados, this makes it easier to sort and organize your photos, instead of keeping their original names.

So for instance, if you took a picture on Mar 31st, 2020 at 10:32:03 AM, your photo could have a name similar to DSC_1234.jpg (if you use Nikon cameras, Cannon use a different prefix I think but also keeping a sequence number). With this tool, your picture would be renamed to 20200331103203.jpg.

Imagine you have 500 photos in your SD card, from different days, with a single command, all of those files would have a neat naming convention that you can use to organize them in folders, easily identify them or just sort them out.

Docker

This tool can be build and run with Docker.

Directly from the Docker Hub image

If you just need to run this tool on any computer with Docker installed (MacOS and Linux, since I haven't used Windows for anything serious for at least 8 years, I wouldn't know if it runs fine there too), you can run:

docker run -it -v `pwd`:/media yorch/photo-renamer /media

This command will rename every image in the current directory using its EXIF creation date, like: 2020033110303.jpg, for easier sorting and photo organization.

ProTip: You can create an alias with the previous command in your .bashrc or .zshrc, and you would be able to call it real fast every time you need to rename your images / photos.

Locally

To build it:

docker build . -t photo-renamer

And to run it:

docker run -it -v `pwd`/temp:/photos photo-renamer /photos

Build

If you have Go installed, you can build the binary by running:

cd src/
go build -o renamer main.go

Or run:

./build-go.sh

You can also run the app directly by:

cd src/
go run main.go

TODO

• Add a flag to backup original files.
• Configurable naming format.
• Make updatemtime as a flag.
• Extract common logic from renamer.go and update-mtime.go into a module.
• Update Travis CI pipeline to upload compiled Go binary to Github releases.
