Exit status for unknown command/subcommand

[n-rodriguez]

When command or subcommand is unknown the default behavior is to print help and exit 0 :

Usage:
  /home/nonroot/.asdf/installs/squarectl/1.4.0/bin/squarectl compose [flags...] [arg...]
Run Docker Compose commands
Flags:
  --config, -c (default: "squarectl.yml")  # Path to config file
  --help                                   # Displays help for the current command.
Subcommands:
  build                                    # Run docker-compose build
  clean                                    # Run docker-compose clean
  config                                   # Run docker-compose config
  down                                     # Run docker-compose down
  exec                                     # Run docker-compose exec
  ps                                       # Run docker-compose ps
  setup                                    # Run docker-compose setup
  start                                    # Run docker-compose start
  stop                                     # Run docker-compose stop
  top                                      # Run docker-compose top
  up                                       # Run docker-compose up
* Done!
Job succeeded

It would be nice to notify user about the missing command, something like Unknow "squarectl compose push" command and to exit 1,

Thank you!

Actually it was my fault : https://github.com/jbox-web/squarectl/blob/3f1be1861d8e46540f53e6bbb26da06d4cf2858f/src/squarectl/cli.cr#L15-L17

I managed to handle the case like this : https://github.com/jbox-web/squarectl/commit/dbabe261dbbd871fed7dd546c92fcb47a81cdd8b
