Which is the most commonly used shell in Linux?

The Bourne-again shell, commonly referred to as Bash, is the most widely used shell in Linux environments. It serves as the default shell for many Linux distributions and is favored due to its rich feature set, ease of use, and compatibility with scripts written for the original Bourne shell. Bash offers advanced functionalities such as command-line editing, job control, and shell functions, which enhance the user experience and efficiency in scripting.

Its popularity stems from its inclusion in major Linux distributions and its utility in both interactive use (for users to type commands) and scripting (for automating tasks). Additionally, many command-line utilities and software packages are specifically designed to work seamlessly with Bash, further solidifying its status as the standard shell for Linux users.
