A Shell in Linux is a command-line interface that allows users to interact with the operating system by typing commands. It acts as an intermediary between the user and the kernel, interpreting and executing commands to manage files, run programs, and perform other system tasks. The shell can also be used for scripting, automating repetitive tasks by writing scripts that execute a series of commands. Common Linux shells include Bash (Bourne Again Shell), Zsh (Z Shell), and Fish (Friendly Interactive Shell), each offering different features like command history, tab completion, and customization options. The shell is a powerful tool for both users and administrators, providing deep control over the system.
