Removes the specified string (case-insensitive) from all filenames in the current directory.

rm-invalid-filenames.sh

sh file-utilities/rm-invalid-filenames.sh [--dry-run]

Recursively removes files and directories whose names contain only non-alphanumeric characters. Use --dry-run to preview what would be deleted without actually removing anything.

Extracts all .7z archives in the current directory using 7z.
