Question Replacing Hex Characters In A File Using awk?
Hi guys,

First off, i'm a complete noob to UNIX and LINUX so apologies if I don't understand the basics!

I have a file which contains a hex value of '0D' at the end of each line when I look at it in a hex viewer.

I need to change it so it contains a hex value of '0D0A0A'

I thought the easiest way would be using awk so I tried this

Code:
awk '{sub("\x0D","\x0D\x0A\x0A")}' filename

It doesn't give me an error but neither does it seem to work. Can anyone tell me what i'm doing wrong?

Thanks for any advice!
