Setting up fish shell

I have always used ZSH on a Mac. There are many ways to customize ZSH. Recently, I felt that my shell was extremely slow. I had experimented with many ZSH plugins and themes. After testing a few options, I decided to switch to the Fish shell. This was not as straightforward as I expected, so I decided to write a blog post about it.

Installation

Install Homebrew: If you don’t have Homebrew, install it by following the instructions on their website.
Install Fish Shell: Open your terminal and run:
```
brew install fish
```
Make Fish the default shell:
- Verify the Fish path with which fish. The path is likely /opt/homebrew/bin/fish.
- Add Fish to the list of known shells. (This is important!)
```
sudo sh -c 'echo /opt/homebrew/bin/fish >> /etc/shells'
```
- Change your default shell:
```
chsh -s /opt/homebrew/bin/fish
```
- Restart your terminal to activate the new shell.

Set up starship.rs (Optional): Fish does not require much additional setup.

curl -sS https://starship.rs/install.sh | sh
echo 'starship init fish | source' >> ~/.config/fish/config.fish

Update VS Code settings to use Fish:

"terminal.integrated.defaultProfile.osx": "fish"
