Nom

Nom is a minimalist bulk renamer for the command line. It's a faster, more colorful, and enhanced version of the simple rn tool.

It provides several methods to batch-process file names: convert to lowercase, uppercase, snake_case, dash-case, or add sequential numbering. Extensions are automatically preserved and lowercased.
