What is the default shell for most Linux distributions?

The default shell for most Linux distributions is Bash, which stands for "Bourne Again SHell." Bash is an enhanced version of the original Bourne shell (sh) and is widely used due to its rich feature set, including command history, job control, and support for shell scripting.

Bash has become the standard shell on many Linux distributions because of its robustness and compatibility with scripts written for earlier shells. It also includes features such as command completion, which enhances user experience and improves productivity. Users typically interact with Bash in terminal sessions for executing commands, running scripts, and managing system tasks.

Other shells like zsh (Z Shell) and fish (Friendly Interactive SHell) are also popular but are not the default for most distributions. They offer unique features and enhancements over Bash, but default installations generally favor Bash, which is reliable and sufficient for most users' needs.
