A Shell provides an interface to Linux and Unix-like systems by interpreting commands and acts as an intermediary between the user and the core workings of the operating system.
Undoubtedly, the bash shell is the most popular one, and some users prefer other shells like ZSH, which is the default shell in macOS. But many shells exist other than these popular ones, with different features and use cases.
In this article, we will take a look at some less popular shells that are actively maintained and provide a different user experience.
