From the cwd, recursively find all rar files, extracting each rar into the directory where it was found, rather than cwd. A nice time saver if you've used wget or similar to mirror something, where each sub dir contains an rar archive. Its likely this can be tuned to work with multi-part archives where all parts use ambiguous .rar extensions but I didn't test this. Perhaps unrar would handle this gracefully anyway?

Extract in the current directory the content of all parted archives. Use the same password for each one.

In order to unrar several files in different subfolders, you just need to launch this command in your parent folder in order to have your files ready for manipulation and already extracted; I did not put anything to delete the original rar files

[Y/N] " response response=${response,,} # tolower if [[ $response =~ ^([Yy]es|YES|[Yy])$ ]]; then echo "rm '$1'" rm $1 fi else echo "'$1' is not a valid file!" fi }
