Fish – A Different Approach to the Command Line

When it comes to Linux, one of the first things that comes to mind is probably the command line and terminal. The shell that processes the statements you write on the command line is offered to users in different versions. Bash, Dash, Zsh, Csh can be given as examples. In this article, we will explain the installation of the Fish shell program.

Fish is a shell program known for being user-friendly. Command completion has the ability to color different forms within the command differently. It offers various recommendations while writing the command and makes these by taking into account the folder you are currently in. You can easily select the suggestions with the arrow keys. One of the features that should be emphasized in terms of ease of use is that it automatically opens help commands in the web browser.
