Features

• Batch file renaming for files under a specified directory (recursively).
• Single-file renaming if a direct path to a file is provided.
• Flexible replacement character: replace whitespace and other undesirable characters with a custom character (_ by default).
• Optional file extension filter: only rename files matching a given extension (e.g., pdf, txt, etc.).
• Safety check: skips renaming if the file is already sanitized.

Requirements

• Perl 5.10+ (or equivalent version that supports the modules used).
• Path::Tiny Perl module.
• (Optionally) App::cpanminus (cpanm) to install dependencies automatically.
