How do I run two commands as part of a single docker-compose "command"?

I’m using Docker v. 20.10.12. I have set up this container in my docker-compose file …

  web:
    restart: always
    build: ./my-web
    ports:
      - "3000:3000"
    expose:
      - '3000'
    env_file: ./my-web/.docker_env
    command: rm -f /app/tmp/pids/*.pid && foreman start -f Procfile.hot
    volumes:
    - ./my-web/:/app
    depends_on:
      - db

When I start using “docker-compose up”, the above container always displays this message

my-web-1 exited with code 0

There is no other info before that. However, if I change the command to be

command: tail -F anything

And then log in to the docker container, I can run

rm -f /app/tmp/pids/*.pid && foreman start -f Procfile.hot

just fine without an errors. How would I run that as part of starting up my Docker container without having to do the manual steps from above?

    Try to put all your commands inside an external sh file.
    in docker-compose use

    command: /bin/sh -c "yourshfile.sh"
