should output the log as the command goes when using travis_wait

[Da-Huang]

When travis_wait is added as prefix, the log should be output as the command goes, instead of after it finishes.

Sorry, that is how the function is implemented right now. If you have suggestions for improvement, you can look at the code here: https://github.com/travis-ci/travis-build/blob/68cdaaf2cfcad54671c3b5896cd867e21a63c737/lib/travis/build/templates/header.sh#L108-145

Hi @Da-Huang

Thanks for your suggestion.

As @BanzaiMan suggested, we are happy to take PRs to improve this. I'm going to close this issue for now as we can discuss any changes within the PR.

Thanks a bundle

@Da-Huang enjoy the following solution:

  long-living-command & # send the long living command to background!

  minutes=0
  limit=30
  while kill -0 $! >/dev/null 2>&1; do
    echo -n -e " \b" # never leave evidences!

    if [ $minutes == $limit ]; then
      break;
    fi

    minutes=$((minutes+1))

    sleep 60
  done

Wow, cool! Thanks, @evilaliv3

I replaced travis_wait with this

 install:
    # Output something every 10 minutes or Travis kills the job
    - while sleep 9m; do echo "=====[ $SECONDS seconds still running ]====="; done &
    - long-living-command
    # Killing background sleep loop
    - kill %1

Thanks @abitrolly, that works perfectly. 👍 I ran into some issues with OSX jobs though, it looks like "minutes" / the m is just ignored by the sleep command there, meaning the keep-alive-output is printed every 9 seconds. Replacing sleep 9m with sleep 540 fixes that (and still works fine on Linux).
