The Fish shell (Friendly Interactive SHell) is a smart and user-friendly command line shell for Unix-like operating systems. It is designed to be easy to use and comes with many features out of the box, such as syntax highlighting, autosuggestions, and a web-based configuration interface. Fish aims to be more interactive and user-friendly compared to other shells like Bash or Zsh.
Fish provides a rich set of features that enhance the user experience. For example, it offers powerful tab completions that are context-aware and can suggest commands, file names, and options as you type. The syntax highlighting feature helps users avoid errors by visually distinguishing between different elements of the command line input. Additionally, Fish has an autosuggestion feature that suggests commands based on your command history, making it faster to repeat frequently used commands.
