About:
brename is a powerful cross-platform command-line utility designed for safe batch renaming of files and directories using regular expressions. It provides a preview mode to show changes before execution, preventing accidental data loss. The tool supports recursive directory traversal and complex pattern matching for sophisticated renaming operations.

Key Features:

Preview mode to safely review changes before applying them
Robust regular expression support with PCRE compatibility
Recursive directory traversal for batch operations
Cross-platform support (Linux, macOS, Windows)

Use Cases:

Standardizing photo filenames from camera exports
Mass renaming source code files during refactoring
Cleaning up downloaded files with inconsistent naming schemes

Alternatives:

rename – Perl-based rename utility with similar regex capabilities but less cross-platform consistency
mmv – Interactive bulk renaming tool with different syntax and approach
