title: Automate Linux tasks
body: <p>I need to launch a command everytime I connect to internet and I was looking to find a way to automate it</p>
  <p>I looked on the crontab but it does't seem as far as I know to allow such automation</p>
  <p>There is any way to do this?</p>
  <p>I would appreciate your help</p>
  <p>Thanks</p>
