Fish now supports setting environment variables for a command easier. Previously you had to do env MIX_ENV=prod mix compile Now you can just do MIX_ENV=prod mix compile But I also generally don't use fish for any scripting, I just use bash for that. But at least some copy-paste commands aren't as difficult to translate now.
