title: Linux Terminal CAT CUT COMMAND
body: <p>I am trying to Save all groups, both system and common, from the group file and alphabetically in a .txt file. but in the terminal the result is:</p>
  <p>the option requires an argument - &quot;d&quot;</p>
  <p>I have the following code so far:</p>
  <p>cat my_group | cut-d &quot;&quot; | sort&gt; grupos.txt</p>
  <p>thanks</p>
