About:
Repren is a command-line utility that performs flexible search and replace operations on file names and file contents. It supports advanced features like multi-pattern replacement, case preservation, and dry-run capabilities. This makes it ideal for complex refactoring or batch renaming tasks that go beyond the capabilities of standard tools.

Key Features:

Rename files and directories using regex patterns
Replace content within files using powerful search and replace
Case preservation and flexible naming schemes
Dry-run mode to preview changes before applying
Handles complex renaming and refactoring scenarios

Use Cases:

Batch renaming photo collections with new numbering schemes
Refactoring codebases by renaming variables and files simultaneously
Cleaning up downloaded files by applying consistent naming conventions

Alternatives:

rename – Standard rename utility, often less powerful than Repren's regex capabilities.
sed – Stream editor for content, but not designed for renaming files or complex batch operations.
