title: Scheduling shell script in crontab
body: <p>I have a shell script that I can run with <code>root</code> user this way:</p>
  
  <p><code>root@vivid-15:~# ./backup.sh</code></p>
  
  <p>It's on <code>/root/backup.sh</code>. Now, how do I schedule it on <code>crontab</code> to execute every day at 01:00 AM? I done this:</p>
  
  <p><code>0 1 * * * root</code></p>
  
  <p>But now I don't know how to proceed the command to do that.</p>
