It contains <code>i</code> when the shell is interactive. For example: </p> <div class="example"> <pre class="example">case "$-" in -*i*) echo This shell is interactive ;; -*) echo This shell is not interactive ;; -esac -</pre> -</div> <p>Alternatively, startup scripts may examine the variable <code>PS1</code>; it is unset in non-interactive shells, and set in interactive shells.
