Shell builtin(yerlesik kabuk) kavrami, isletim sistemi servislerine erismek icin kernel uzerinde calisan shell icerisinde tanimli bir komut ya da fonksiyon olarak adlandirilir. Harici bir program komutu shell üzerinde yorumlanarak yüklenir ve çalıştırılır. Aksine bir shell builtin komutu ise shell uzerinde tanimli oldugundan dogrudan cagrilabilmesi sayesinde harici bir programi cagirma islemine gore daha hizlidir. Cunku komut shell uzerinde hali hazırda tanimli oldugundan, sistem uzerinde herhangi bir yukleme islemi yapilmaz.

Bourne shell ve C shell en popüler shell yorumlayıcıları(interpreter) arasındadır. Unix sistemlerinde cd, type, ls gibi komutlar shell-builtin komutları olarak adlandırılır.
