Back to a vanilla (fish) shell

• Updated on 2024-09-06: Since exa is no longer maintained, we need to add the following in ~/.config/fish/config.fish instead:

if type -q eza
    alias ll "eza -l -g --icons"
    alias lla "ll -a"
end

• Decided to say goodbye to oh-my-zsh after a decade and pursue the pure joy of simplicity.¹
• Uninstalled oh-my-zsh with uninstall_oh_my_zsh. (This is handy, I’ll give it that.)
• Installed fish from Homebrew brew install fish
• Followed this gist to set fish as default shell. The documentation might be outdated since the default path to fish is now different: /opt/homebrew/bin/fish. Thanks to macOS’s updates in recent years.
• Added the list of “known shells”: sudo sh -c 'echo /opt/homebrew/bin/fish >> /etc/shells'
• Restarted the CLI and ran command: chsh -s /opt/homebrew/bin/fish.
• Restarted the CLI and added brew binaries in fish path: fish_add_path /opt/homebrew/bin
• Added a few aliases frequently used in ~/.config/fish/config.fish.
• Added a snippet to use exa eza easily. Credit to Ruihao Li.
• Used cmd+shift+p in VSC to install code command in PATH.
• Used fish_config to customize my shell prompt.

Now I’m in peace now.
