Be aware inside *NIX flavours!

The first in the code prints "Hello World." on the next line immediatley followed by the prompt.
The second with "\n" gives a newline for the prompt.
The third with "\r", (^M), overwrites itself so you see nothing.
Fourth and Fifth, "\r\n", "\n\r", are _effectively_ the same but are NOT.

Carraiage Return does EXACTLY what it says on the tin as does Newline...

Code:

Hello World.AMIGA:barrywalker~> printf "Hello World.\n"
Hello World.
AMIGA:barrywalker~> printf "Hello World.\r"
AMIGA:barrywalker~> printf "Hello World.\r\n"
Hello World.
AMIGA:barrywalker~> printf "Hello World.\n\r"
Hello World.
AMIGA:barrywalker~>

I suspect the you need '\r" added and not swapped for Windows reasons...

HI
\003\HIUL\003\HIJ\003 

You don't want to replace \n with <carriage return>, but with the <line feed> (newline, ^J, 0x0A) char to produce your desired output. So use Yoda's proposal. With <CR>, your output would look like
Code:
HI\003\HIUL\003\HIJ\003

as the two first lines would be overwritten!
