title: What is long-format in Linux?
body: <p>What exactly is the <em>long format</em> in Linux?.
  I am a newbie into programming and Linux. So I was taking a tutorial in terminal operations.
  This command <code>ls -l</code> is said to list the files in the working directory in <em>long format</em>.
  Can somebody explain or give resources explaining about the <em>long format</em> and its use?</p>
