Bash #9 - Fish shell on WSL2/Ubuntu

Today we’ll look at a Linux shell called fish, which stand for “friendly interactive shell” as an alternative shell to bash in Linux distros.
Syntax highlighting for errors, misspelled commands and options, mismatched parenthesis and quotes. The great thing about fish is that this is done while typing.
Using the manual page data, fish helps you by pressing the tab key to auto complete. Simply start typing and hit tab to get suggestions.
Inline search history: where you can start typing and then use the up and down arrow keys to select previous commands that started that way.
With auto suggestion it provides feedback based on the content of a directory or your history.
#terminal #linux #wsl #shell

Hi, I am facing issue where fish is taking lot of time to output, the prompt is taking time, 2 or 3 seconds just to clear, did you face any such issue?
