What is the default shell for most Linux distributions?

The default shell for most Linux distributions is the Bourne Again Shell, commonly known as bash. Bash serves as an enhanced version of the original Bourne Shell (sh) with additional features that provide better usability and functionality like command line editing, improved variable handling, and job control.

Due to its widespread adoption and association with Linux, bash is the standard shell available in many distributions, making it the most commonly encountered shell by users and system administrators. This high level of usage ensures extensive community support and a wealth of resources for learning and troubleshooting, further cementing its status as the default shell in numerous Linux environments.

Other shells, while they have their own unique features and capabilities, are generally not set as the default in mainstream distributions, making bash the de facto choice for most users.
