Migrating from ZSH to Fish
I've always been using ZSH + Oh My Zsh for my shell configuration, which I have been happy with. But I recently got the urge to try out something new, and I decided to try out fish as it includes many useful features without needing extra configuration. It also has a sweet name.
A note on Fish
Fish is not POSIX compliant, meaning you cannot use it to run your regular bash scripts. Fish-programs has to be written using the fish syntax, which seems easy enough to learn. I do little bash scripting for my regular workflow, and I plan on using fish solely as an interactive shell, so I do not think I will notice this very much
Installation
I used homebrew for a quick and easy installation:
<span><span style="color: var(--shiki-token-function)">brew</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">install</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">fish</span></span>
<span></span>I then added fish to my list of known shells, and used chsh to set fish as default. After doing these steps, I had to sign out and back in again.
<span><span style="color: var(--shiki-token-function)">sudo</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">bash</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">-c</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string-expression)">'echo $(which fish) >> /etc/shells'</span></span>
<span><span style="color: var(--shiki-token-function)">chsh</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string)">-s</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-string-expression)">$(</span><span style="color: var(--shiki-token-function)">which</span><span style="color: var(--shiki-token-string-expression)"> </span><span style="color: var(--shiki-token-string)">fish</span><span style="color: var(--shiki-token-string-expression)">)</span></span>
<span></span>I also had to use the fish_add_path command for fish to recognize programs installed by homebrew:
<span><span style="color: var(--shiki-token-function)">fish_add_path</span><span style="color: var(--shiki-color-text)"> /opt/homebrew/bin</span></span>
<span></span>Configuring fish
As I mentioned earlier, fish is very useable without any configuration, which I like. I, therefor, have decided to keep my config as clean as possible, without relying on any plugins.
The first thing I did was to set the fuck alias, and disable the autosuggestion by default, as I found it distracting. I did this in .config/fish/config.fish.
<span><span style="color: var(--shiki-token-comment)"># ~/.config/fish/config.fish</span></span>
<span></span>
<span><span style="color: var(--shiki-token-function)">thefuck</span><span style="color: var(--shiki-color-text)"> --alias </span><span style="color: var(--shiki-token-keyword)">|</span><span style="color: var(--shiki-color-text)"> </span><span style="color: var(--shiki-token-keyword)">source</span></span>
<span><span style="color: var(--shiki-token-function)">set</span><span style="color: var(--shiki-color-text)"> -g fish_autosuggestion_enabled 0</span></span>
<span></span>I then found a pretty greeting-function and modified it a bit to only print the greeting for large windows that open in ~, as I do not want it cluttering the screen while I'm working on something.
<span><span style="color: var(--shiki-token-comment)"># ~/.config/fish/functions/fish_greeting.fish</span></span>
<span></span>

<span></span>Neovim configuration
I installed fish grammar for treesitter to get syntax highlighting in Neovim. I also had to install ripgrep from homebrew to get telescope live grep working.
:TSinstall fish
brew install ripgrep
Thoughts
I've been using fish for the past couple of days now, and I have to say that I like it alot. After configuring everything, I've noticed how fast the prompt appears compared to Oh My Zsh. I've also been really impressed with fish_config, which let's you do some configuration from a web interface. This was really useful when deciding on colors for my prompt. I've also been liking the prevd and nextd commands which are mapped to alt + left/right arrow. I also really like that ctrl+c is shown after terminating stuff.
If you want to copy my setup, feel free to check out my dotfiles!
