title: Not getting the output from shell script in Gitlab CI
body: <p>I have set up a gitlab runner on my windows. I have a <code>build.sh</code> script in which I am just echoing "Hello world". I have provided these lines in my <code>gitlab-ci.yml</code> file:</p>
  
  <pre><code>build:
      stage: build
      script:
          - ./build.sh
  
  </code></pre>
  
  <p>The runner executes this job but does not print the echo command which I have mentioned in the <code>build.sh</code> file. But if I changed the extension to <code>.bat</code> it works and shows me the output. The <code>gitlab-runner</code> is set up for shell. What can be the possible reason? or I am missing something?</p>
