What is the default shell in most Linux distributions?

Bash, or the Bourne Again SHell, is the default shell in most Linux distributions due to its rich feature set, compatibility with the original Bourne shell (sh), and its widespread use in scripts and command-line interaction. Bash includes a variety of enhancements such as command-line editing, job control, and control structures, making it a powerful and user-friendly choice for users and system administrators alike.

This choice is also supported by its strong community, extensive documentation, and availability in nearly all Linux distributions, which promotes consistency across different environments. Other shells like Csh, Zsh, and Ksh do have their own unique features and loyal user bases, but they do not have the same level of default adoption as Bash in today’s Linux systems. This widespread use of Bash helps simplify the learning curve for new users, as they can expect similar behavior and scripting conventions regardless of the Linux distribution they choose.
