> Fish is cool! I keep wanting to use it, but the inertia of Bourne shell is hard to overcome.

Back when I tried Fish some like 5 or 6 years ago I think, I was really attracted by how you could write multiline commands in a single prompt. I left it, though, when I found out that its pipes were not true pipes. The second command in a pipeline did not run until the first finished, and that sucked and made it useless when the first command was never meant to finish on its own or when it should've been the second command to determine when the first should finish.

It seems they've fixed that, but now I found that you can also write multiline commands in a single prompt in zsh, and I can even use j/k to move between the lines, and have implemented tab to indent the current line to the same indentation as the previous line in the same prompt. Also, zsh has many features that make code significantly more succinct, making it quicker to write. This seems to go right against the design principle of fish of being a shell with a simpler syntax, so now I don't see the point of even trying to move to it.

If you are interested, I use a configuration for zsh that I see as "a shell with features like fish and a syntax like bash"

In .zshrc:

    ZSH="$HOME/.oh-my-zsh"

    if [ ! -d "$ZSH" ]; then
        git clone --depth 1 git://github.com/robbyrussell/oh-my-zsh.git "$ZSH"
    fi

    DEFAULT_USER=jraph

    plugins=(zsh-autosuggestions) # add zsh-syntax-highlighting if not provided by the system

    source "$HOME/.oh-my-zsh/oh-my-zsh.sh"

    PROMPT="%B%{%F{green}%}[%*] %{%F{red}%}%n@%{%F{blue}%}%m%b %{%F{yellow}%}%~ %f%(!.#.$) "
    RPROMPT="[%{%F{yellow}%}%?%f]"

    EDITOR=nano

    if [ -f /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh ]; then
        source /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh # Debian
    elif [ -f /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh ]; then
        source /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh # Arch
    fi

Relevant packages to install: git zsh zsh-syntax-highlighting

Then:

    zsh

WARNING: it downloads and executes Oh My Zsh automatically using git. You may want to review it before.

If it suits you:

    chsh

Works on macOS, Arch, Debian, Ubuntu, Fedora, Termux and probably in most places anyway.

You may need this too:

    export TERM="xterm-256color"
