The scripts under `d` are helpers that automatically execute commands inside the container - I would suggest looking at them if you’re curious:

```bash
± |master ✓| → cat d/rake
#!/bin/bash

PARAMS="$@"
CMD="cd /src && RUBY_GLOBAL_METHOD_CACHE_SIZE=131072 LD_PRELOAD=/usr/lib/libjemalloc.so RAILS_ENV=${RAILS_ENV:=development} bundle exec rake $PARAMS"
docker exec -it -u discourse:discourse discourse_dev /bin/bash -c "$CMD"

```
