  <title>Login shells</title>

  <p>Shells in UNIX based systems can be started up in login and non-login
  modes:</p>

      <title>Login shell</title>
      <p>A login shell is a shell given to a user upon login into their user
      account. This is initiated by using the <cmd>-l</cmd> or
      <cmd>--login</cmd> option, or placing a dash as the initial character
      of the command name, for example invoking <cmd>bash</cmd> as
      <cmd>-bash</cmd>.</p>
    </item>
    <item>
      <title>Sub shell</title>
      <p>Sub shell, also called a non-login shell is a shell started after
      the login process without the <cmd>-l</cmd> or <cmd>--login</cmd>
      option and without an extra dash before the command name.</p>
    </item>
  </terms>

  <p>The general cases for having a login shell include:</p>
  <list>
    <item>
      <p>Accessing your computer remotely using <app>ssh</app>.</p>
    </item>
    <item>
      <p>Simulating an initial login shell with <cmd>bash -l</cmd> or
      <cmd>sh -l</cmd>.</p>
    </item>
    <item>
      <p>Simulating an initial root login shell with <cmd>sudo -i</cmd>.</p>
    </item>
  </list>
