notes:
I could have used the -e flag in echo, however other lines
nearby use printf so I figured it would be smart to stay consistent.
Also, I see the usage of `command printf`. Not 100% if this is
necessary. I don't see why printf would be redefined in the shell.
If we're doing this, then we might as well prefix every call
to a builtin or binary with `command` _just to be safe_.
