title: Interrupt an order like: fg ; next_program
body: <p>I have been reading this solution: <a href="https://stackoverflow.com/a/35587710">https://stackoverflow.com/a/35587710</a> for the case when you have executed a program with a long execution time and just after that you realize you wanted to execute another program when the first one finish. The solution says use:</p>
  
  <pre><code>Ctrl Z
  fg ; python next_program.py
  </code></pre>
  
  <p>If what I wanted to execute was badly written due to a typo, i.e., I wrote <code>fg ; python my_prograM.py</code> and I wanted to do <code>fg ; python my_program.py</code>, how can I cancel the first fg and launch the second one? Thanks.</p>
