A shell in Linux is a command-line interface (CLI) that allows users to interact with the operating system by executing commands. It’s an environment where users can run scripts, manage files, install software, and more. The shell interprets user commands and translates them into actions performed by the system. Shells are essential tools for system administrators and developers, providing powerful capabilities for automation, configuration, and system management. Different shells offer various features and enhancements, making them suitable for different tasks and user preferences. Understanding the differences between these shells can help users choose the right tool for their needs and improve their efficiency in managing Linux systems.
There are different types of shells in Linux, each with its own features. Some common ones include:
