Basit bir FOR döngüsü

Bir kuruluşta veri bilimci olarak çalışıyorsun. Bölümlerin yakın zamanda birleşmesi nedeniyle içinde birçok dosya olan bir klasörü devraldın. .R betiklerinin işin için faydalı olabileceğini biliyorsun ama içinde ne olduğunu tam olarak bilmiyorsun.

inherited_folder/ dizinindeki .R ile biten tüm dosyaları dolaşacak basit bir Bash betiği yaz ve adlarını yazdır ki elindeki betiklerin ne tür olduğuna hızlıca bakabilesin. Umarız dosya adları işe yarar!
