{ lib, stdenv
, writeShellScriptBin
, nix-index, gnugrep
}:

with lib;

stdenv.mkDerivation {
  name = "comma";
  version = "1.0";
  src = writeShellScriptBin "comma" ''
    if [ -z "$1" ]; then
      echo "You must specify a command" > /dev/stderr
      exit 1
    else
      command="$1"
      shift
    fi

    packages=$(${nix-index}/bin/nix-locate -r "bin/$command(-wrapped)?$") || { >&2 echo "No package found"; exit 2;}

There is also comma for basically the same thing.

Thanks for the shoutout!

This is, as nrdxp said, pretty much an implementation of comma. Comma was out of date at the time, so I went and implemented my own.

Comma is very maintained now (thanks @Artturin!), and I 100% recommend it over my stopgap thingy. I’ll probably switch over too.
