Zsh, Bash and Fish are all Unix shells but they differ in several ways. Zsh is highly customizable with features like spelling correction, shared command history, and themeable prompts. It also supports most of the Bash features, making it a popular choice for those transitioning from Bash. However, unlike Bash, Zsh isn’t installed by default on many systems.
Fish, on the other hand, emphasizes user-friendliness and interactivity. Its syntax differs significantly from both Bash and Zsh, which can be a hurdle for new users. It offers features like autosuggestions and web-based configuration that aren’t available in Bash or Zsh.
