Renamer - The perfect tool to easily rename your files

Renamer is a fast and light utility to rename your files on all file systems. It allows you to do a lot of renaming tasks without requiering any specific knowledge. Everything is done from the command-line and you can use it from a script-shell or another program.

Renamer can:

  • lowercase a list of filenames

  • uppercase a list of filenames

  • delete white-spaces of filenames

  • replace underscores by spaces in filenames

  • capitalize filenames

  • rename files using a specified basename followed by an incremental number

  • rename files from their actual extension to a specified one

  • do recursive actions

  • and more (Renamer is always evolving) …

  • is developed from scratch (not based on any other code)

  • multi-platform (GNU/Linux, *BSD, Windows & other)

  • 100% GPL & free
