Can you list and describe the main shells used in Linux?

In Linux, there are several popular shells that provide user interaction with the operating system through the command line. The main ones are:

• Bash (Bourne Again Shell) — the most common shell by default in many Linux distributions. Supports scripts, extensions, auto-completion, command history.

• sh (Bourne Shell) — a classic shell on which many others are based. Less functional but compatible with most scripts.

• zsh (Z Shell) — an advanced shell with powerful auto-completion, themes, plugins. Often used to enhance interactive work.

• csh (C Shell) and tcsh — shells with syntax similar to the C language, convenient for users familiar with this language. tcsh is an extended version of csh with auto-completion.

• fish (Friendly Interactive Shell) — a modern shell with a user-friendly syntax, syntax highlighting, auto-completion, and a friendly interface.

Each shell has its features and is suitable for different tasks — from simple command execution to complex scripting and automation.
