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 a widely used command processor that allows users to interact with the operating system by entering commands. It is an enhanced version of the original Bourne shell (sh), providing features such as command-line editing, job control, and improved scripting capabilities.

One reason Bash is the default is that it supports a wide set of features and compatibility with scripts written for the Bourne shell, making it a robust choice for users transitioning from other Unix-like systems. Its extensive community support, documentation, and rich feature set make it a go-to shell for both novice and experienced Linux users.

While other shells like Fish (Friendly Interactive SHell), Csh (C Shell), and Sh (the original Bourne Shell) also exist, they are not as commonly set as the default in modern Linux distributions. Some distributions may offer these alternatives as options, but Bash's versatility and widespread acceptance have secured its place as the standard shell in most environments.
