title: Add suffix to each line with shell script
body: <p>I need to add some words at the end of each line of a text file. How can I do this with a Bash script?</p>
  
  <p>Example: add the word <code>done</code> at the end of each line:</p>
  
  <pre class="lang-none prettyprint-override"><code>line1 abcdefg done
  line2 abcdefg done
  line3 abcdeft done
  </code></pre>
