I think these three point are important:</p> <ul> <li>easy to use</li> <li>helpful</li> <li>play well with others</li> </ul> <!-- more --> <p>Bash is commonly used to write command line apps, but I can never shrug of the feeling of shame of writing a bash script with more than 30 lines. That&rsquo;s why I&rsquo;m shaking things up here and showing how to use ruby instead. I&rsquo;ll be using the optparse gem so you need to do a <code>gem install optparse</code> before trying out the shown examples.</p>
