If you can have an alias like: ``` aliases: rails: app exec -p rails ``` Then `kamal rails db:migrate:status` will execute `kamal app exec -p rails db:migrate:status`. So this works, we'll allow multiple arguments `app exec` and `server exec` to accept multiple arguments. The arguments are combined by simply joining them with a space. This means that these are equivalent: ``` kamal app exec -p rails db:migrate:status kamal app exec -p "rails db:migrate:status" ``` If you want to pass an argument with spaces, you'll need to quote it: ``` kamal app exec -p "git commit -am \"My comment\"" kamal app exec -p git commit -am "\"My comment\"" ```
