Normally to overwrite a function you can use builtin or a path to a binary.

But specifically when I'm overwriting cd it's a bit clunky:

source /opt/homebrew/share/fish/functions/cd.fish
functions -e _cd_orig
functions -c cd _cd_orig

function cd -d "quickly cd and ls" -w cd
    if test (count $argv) -eq 1
        if test ! -e $argv[1] -a "$argv[1]" != -
            new -d $argv[1]
        end
    end
    _cd_orig $argv
    ls-preview
end

Is there an easier way to do this?

There's not an easier way when you want to keep the old function around instead of replace it, no.

You could test if _cd_orig and cd exist before sourcing and renaming:

if not functions -q _cd_orig
    if not functions -q cd
        source /opt/homebrew/share/fish/functions.cd.fish
    end
    functions -c cd _cd_orig
end

Though it's not a big deal, unless you are sourcing the file this belongs in often.
