To convert CBR to CBZ recursively in a directory structure, you can use a script. Is a script for Linux/Unix (Bash) or Windows with tools like Git Bash installed.

What It Does:

1. Finds all .cbr files recursively using find.
2. Extracts each .cbr into a temporary folder using unrar.
3. Compresses the extracted content into a .cbz using zip.
4. Optionally deletes the original .cbr file.

Notes:

• Safety: It won't overwrite existing .cbz files unless explicitly set.
• Dependencies: Ensure unrar and zip are installed.
• Customization: Uncomment the line to delete .cbr files after conversion if desired.
