Fishshell is a Unix shell that provides a more user-friendly and interactive command-line interface than the traditional Bash shell. It features syntax highlighting, autosuggestions, and a powerful scripting language that can be used to automate tasks and customize the shell environment. Fishshell is designed to be easy to use and learn, making it a popular alternative to Bash for both novice and experienced Linux users.
Fishshell can be used in the same way as any other Unix shell. To start using Fishshell, simply open a terminal window and type
fish. This will launch the Fishshell prompt, where you can enter commands and interact with the shell.
