What are the Different Types of Shells in Linux?

Shells act as an interface between users and the kernel, allowing command execution and system interaction. Key Linux shells include the Bourne shell (sh), Bash (GNU Bourne-Again shell), C shell (csh), Korn shell (ksh), and Z Shell (zsh). Each shell has unique features suitable for specific tasks, such as Bourne's compact nature, Bash’s command recall, C shell’s aliasing, Korn shell’s script compatibility, and Zsh's customization.
