I don't understand how to properly format this particular thing (in block characters)

---

Just to fool around with script making, I made one that (I believe?) should open a terminal at startup: 

#!/bin/bash
 #start terminal at startup
 #/usr/bin/gnome-terminal

---

The bit with the `#` (hash, pound or octothorpe symbol) causes the three lines to conform to one line, after I indented properly for block characters.

Without indents, I get this:

---

!/bin/bash
==========

start terminal at startup
=========================

/usr/bin/gnome-terminal
=======================

---

How would I use block characters in the presence of the hash or pound sign?
