What is the default shell for most Linux distributions?

Bash, or the Bourne Again SHell, is the default shell for most Linux distributions due to its versatility and user-friendly features. It combines elements of the original Bourne shell (sh) as well as additional functionalities that enhance user experience and script-writing capabilities. Bash supports command-line editing, job control, and various programming constructs, making it suitable for both novice and experienced users.

The widespread adoption of Bash is also a result of its compatibility with many scripts and systems previously written for the Bourne shell while offering several enhancements, such as arrays and improved variable handling. Most Linux distributions, including well-known ones like Ubuntu, Fedora, and CentOS, have chosen Bash as the default shell, which contributes to a consistent experience across different environments.

While other shells like Sh, Csh, and Tcsh are available and serve specific use cases or preferences, Bash remains the predominant choice in the Linux community for its robustness and functionality.
