<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>
